They are force-free and can be described as hydrodynamic force dipoles: pushers or pullers. This modelling description is broadly used in biological physics and active matter research, and it has successfully predicted, for example, the superfluid behaviour of suspensions of pushers or the bend instability and emergence of turbulent flows in active nematics. However, this description accounts only for the translational motion of the swimming body and neglects the effects of hydrodynamic torque dipoles, which are relevant to bacteria with rotary motor-driven flagella, such as swimming Escherichia coli. Here we show that the torque dipole of confined swimming E. coli can power the persistent rotation of symmetric discs. The torque dipole leads to a traction force on the discs, an additive mechanism that is both contactless and independent of the orientation of the bacteria. Our results indicate that the torque dipole of swimming E. coli is notable in confined geometries, which is relevant to bacterial transport through porous materials, biofilms and the development of chiral fluids.","lang":"eng"}],"has_accepted_license":"1","day":"27","citation":{"apa":"Grober, D.

by Richard Feynman’s 1959 lecture and the 1966 film Fantastic Voyage, the field of micro/nanorobots has evolved from science fiction to reality, with significant advancements in biomedical and environmental applications. Despite the rapid progress, the deployment of functional micro/nanorobots remains limited. This review of the technology roadmap identifies key challenges hindering their widespread use, focusing on propulsion mechanisms, fundamental theoretical aspects, collective behavior, material design, and embodied intelligence. We explore the current state of micro/nanorobot technology, with an emphasis on applications in biomedicine, environmental remediation, analytical sensing, and other industrial technological aspects. Additionally, we analyze issues related to scaling up production, commercialization, and regulatory frameworks that are crucial for transitioning from research to practical applications.

In contrast, the energy input of the individual components controls the behavior of synthetic or living active matter. Great progress has been made in understanding the emergent phenomena in active fluids, though their inability to resist shear forces hinders their practical use. This motivates the exploration of active solids as shape-shifting materials, yet, we lack controlled synthetic systems to devise active solids with unconventional properties. Here we build active elastic beams from dozens of active colloids and unveil complex emergent behaviors such as self-oscillations or persistent rotations. Developing tensile tests at the microscale, we show that the active beams are ultrasoft materials, with large (nonequilibrium) fluctuations. Combining experiments, theory, and stochastic inference, we show that the dynamics of the active beams can be mapped on different phase transitions which are tuned by boundary conditions. More quantitatively, we assess all relevant parameters by independent measurements or first-principles calculations, and find that our theoretical description agrees with the experimental observations. Our results demonstrate that the simple addition of activity to an elastic beam unveils novel physics and can inspire design strategies for active solids and functional microscopic machines."}],"external_id":{"arxiv":["2508.20642"]},"scopus_import":"1","ec_funded":1,"DOAJ_listed":"1","issue":"4","status":"public","PlanS_conform":"1","publication":"Physical Review X","date_updated":"2025-12-01T07:44:06Z","file_date_updated":"2025-12-01T07:30:00Z"},{"citation":{"chicago":"Carrasco, Celso, Quentin Martinet, Zaiyi Shen, Juho Lintuvuori, Jérémie A Palacci, and Antoine Aubret. “Characterization of Nonequilibrium Interactions of Catalytic Microswimmers Using Phoretically Responsive Nanotracers.” <i>ACS Nano</i>.

They sustain chemical gradients and fluid flows that propel them by phoresis. This leads to unconventional behavior and collective dynamics, such as self-organization into complex structures. Characterizing the nonequilibrium interactions of microswimmers is crucial for advancing our understanding of active systems. However, this remains a challenge owing to the importance of fluctuations at the microscale and the difficulty in disentangling the different contributions to the interactions. Here, we show a massive dependence of the nonequilibrium interactions on the shape of catalytic microswimmers. We perform tracking experiments at high throughput to map interactions between nanocolloidal tracers and dimeric microswimmers of various aspect ratios. Our method leverages dual tracers with differing phoretic mobilities to quantitatively disentangle phoretic motion from hydrodynamic advection. This approach is validated through experiments on single chemically active sites and on immobilized catalytic microswimmers. We further investigate the activity-driven interactions of free microswimmers and directly measure their phoretic interactions. When compared to standard models, our findings highlight the important role of osmotic flows for microswimmers near surfaces and reveal an enhanced contribution of hydrodynamic advection relative to phoretic motion as the size of the microswimmer increases. Our study provides robust measurements of the nonequilibrium interactions from catalytic microswimmers and lays the groundwork for a realistic description of active systems.","lang":"eng"}],"quality_controlled":"1","type":"journal_article","OA_place":"repository","date_published":"2025-03-11T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://hal.science/hal-04682818v2"}],"intvolume":"        19","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2025","publication":"ACS Nano","date_updated":"2025-10-16T10:26:59Z","isi":1,"issue":"11","scopus_import":"1","status":"public","page":"11133-11145","publication_status":"published","date_created":"2025-03-23T23:01:26Z","title":"Characterization of nonequilibrium interactions of catalytic microswimmers using phoretically responsive nanotracers","OA_type":"green","oa_version":"Submitted Version","publication_identifier":{"eissn":["1936-086X"],"issn":["1936-0851"]},"volume":19,"author":[{"full_name":"Carrasco, Celso","last_name":"Carrasco","first_name":"Celso"},{"full_name":"Martinet, Quentin","last_name":"Martinet","orcid":"0000-0002-2916-6632","first_name":"Quentin","id":"b37485a8-d343-11eb-a0e9-df8c484ef8ab"},{"full_name":"Shen, Zaiyi","last_name":"Shen","first_name":"Zaiyi"},{"first_name":"Juho","full_name":"Lintuvuori, Juho","last_name":"Lintuvuori"},{"first_name":"Jérémie A","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","orcid":"0000-0002-7253-9465","last_name":"Palacci","full_name":"Palacci, Jérémie A"},{"first_name":"Antoine","last_name":"Aubret","full_name":"Aubret, Antoine"}],"month":"03","department":[{"_id":"JePa"}],"project":[{"_id":"eb99c9bb-77a9-11ec-83b8-9f8cffa20a35","grant_number":"P35206","name":"Emergent Behavior in Spinning Active Matter"}],"article_type":"original","oa":1,"doi":"10.1021/acsnano.4c18078","acknowledgement":"The authors thank M.

However, the space of accessible structures in which micron-scale particles can be organized by thermal forces is limited, owing to the slow dynamics and metastable states. Active agents in a passive fluid generate forces and flows, forming a bath with active fluctuations. Two unanswered questions are whether those active agents can drive the assembly of passive components into unconventional states and which material properties they will exhibit. Here we show that passive, sticky beads immersed in a bath of swimming Escherichia coli bacteria aggregate into unconventional clusters and gels that are controlled by the activity of the bath. We observe a slow but persistent rotation of the aggregates that originates in the chirality of the E. coli flagella and directs aggregation into structures that are not accessible thermally. We elucidate the aggregation mechanism with a numerical model of spinning, sticky beads and reproduce quantitatively the experimental results. We show that internal activity controls the phase diagram and the structure of the aggregates. Overall, our results highlight the promising role of active baths in designing the structural and mechanical properties of materials with unconventional phases.","lang":"eng"}],"_id":"13971","language":[{"iso":"eng"}],"external_id":{"isi":["001037346400005"]},"type":"journal_article","quality_controlled":"1","date_published":"2023-11-01T00:00:00Z","intvolume":"        19","year":"2023","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","ddc":["530"],"author":[{"id":"abdfc56f-34fb-11ee-bd33-fd766fce5a99","first_name":"Daniel","last_name":"Grober","full_name":"Grober, Daniel"},{"last_name":"Palaia","full_name":"Palaia, Ivan","first_name":"Ivan","id":"9c805cd2-4b75-11ec-a374-db6dd0ed57fa","orcid":" 0000-0002-8843-9485 "},{"last_name":"Ucar","full_name":"Ucar, Mehmet C","id":"50B2A802-6007-11E9-A42B-EB23E6697425","first_name":"Mehmet C","orcid":"0000-0003-0506-4217"},{"full_name":"Hannezo, Edouard B","last_name":"Hannezo","orcid":"0000-0001-6005-1561","first_name":"Edouard B","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0002-7854-2139","id":"bf63d406-f056-11eb-b41d-f263a6566d8b","first_name":"Anđela","full_name":"Šarić, Anđela","last_name":"Šarić"},{"last_name":"Palacci","full_name":"Palacci, Jérémie A","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","first_name":"Jérémie A","orcid":"0000-0002-7253-9465"}],"volume":19,"article_type":"original","project":[{"name":"IST-BRIDGE: International postdoctoral program","call_identifier":"H2020","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","grant_number":"101034413"},{"name":"Non-Equilibrium Protein Assembly: from Building Blocks to Biological Machines","call_identifier":"H2020","_id":"eba2549b-77a9-11ec-83b8-a81e493eae4e","grant_number":"802960"},{"grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships"}],"month":"11","department":[{"_id":"EdHa"},{"_id":"AnSa"},{"_id":"JePa"}],"acknowledgement":"D.G. and J.P. thank E.

They restrain degrees of freedom and channel power into a specified motion. Building and powering small-scale cogwheels are key steps toward feasible micro and nanomachinery. Assembly, energy injection, and control are, however, a challenge at the microscale. In contrast with passive gears, whose function is to transmit torques from one to another, interlocking and untethered active gears have the potential to unveil dynamics and functions untapped by externally driven mechanisms. Here, it is shown the assembly and control of a family of self-spinning cogwheels with varying teeth numbers and study the interlocking of multiple cogwheels. The teeth are formed by colloidal microswimmers that power the structure. The cogwheels are autonomous and active, showing persistent rotation. Leveraging the angular momentum of optical vortices, we control the direction of rotation of the cogwheels. The pairs of interlocking and active cogwheels that roll over each other in a random walk and have curvature-dependent mobility are studied. This behavior is leveraged to self-position parts and program microbots, demonstrating the ability to pick up, direct, and release a load. The work constitutes a step toward autonomous machinery with external control as well as (re)programmable microbots and matter."}],"language":[{"iso":"eng"}],"quality_controlled":"1","type":"journal_article","date_published":"2023-01-01T00:00:00Z","intvolume":"         5","article_number":"2200129","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","ddc":["530"],"year":"2023","date_updated":"2024-10-09T21:04:56Z","publication":"Advanced Intelligent Systems","isi":1,"file_date_updated":"2023-04-17T06:44:17Z","issue":"1","status":"public","file":[{"content_type":"application/pdf","success":1,"date_created":"2023-04-17T06:44:17Z","file_size":2414125,"access_level":"open_access","relation":"main_file","file_id":"12840","creator":"dernst","date_updated":"2023-04-17T06:44:17Z","checksum":"d48fc41d39892e7fa0d44cb352dd46aa","file_name":"2023_AdvancedIntelligentSystems_Martinet.pdf"}],"publication_status":"published","title":"Rotation control, interlocking, and self‐positioning of active cogwheels","date_created":"2023-04-12T08:30:03Z","oa_version":"Published Version","arxiv":1,"publication_identifier":{"issn":["2640-4567"]},"author":[{"first_name":"Quentin","id":"b37485a8-d343-11eb-a0e9-df8c484ef8ab","orcid":"0000-0002-2916-6632","last_name":"Martinet","full_name":"Martinet, Quentin"},{"first_name":"Antoine","last_name":"Aubret","full_name":"Aubret, Antoine"},{"id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","first_name":"Jérémie A","orcid":"0000-0002-7253-9465","full_name":"Palacci, Jérémie A","last_name":"Palacci"}],"volume":5,"department":[{"_id":"JePa"}],"month":"01","article_type":"original","doi":"10.1002/aisy.202200129","oa":1,"acknowledgement":"Army Research Office.

Here, we demonstrate the programmable assembly of active particles into autonomous metamachines using optical templates. Metamachines, or machines made of machines, are stable, mobile and autonomous architectures, whose dynamics stems from the geometry. We use the interplay between anisotropic force generation of the active colloids with the control of their orientation by local geometry. This allows autonomous reprogramming of active particles of the metamachines to achieve multiple functions. It permits the modular assembly of metamachines by fusion, reconfiguration of metamachines and, we anticipate, a shift in focus of self-assembly towards active matter and reprogrammable materials."}],"external_id":{"isi":["000714754400010"],"pmid":["34737315"]},"type":"journal_article","quality_controlled":"1","has_accepted_license":"1","day":"04","citation":{"mla":"Aubret, Antoine, et al. “Metamachines of Pluripotent Colloids.” <i>Nature Communications</i>, vol. 12, no. 1, 6398, Springer Nature, 2021, doi:<a href=\"https://doi.org/10.1038/s41467-021-26699-6\">10.1038/s41467-021-26699-6</a>.","ieee":"A.

In this work, we show how one can perform sensitive measurements of neutral polymer coating on colloidal particles using a commercial zetameter and salt solutions. By systematically varying the Debye length, we study the mobility of the polymer-coated particles in an applied electric field and show that the electrophoretic mobility of polymer-coated particles normalized by the mobility of non-coated particles is entirely controlled by the polymer brush and independent of the native surface charge, here controlled with pH, or the surface–ion interaction. Our result is rationalized with a simple hydrodynamic model, allowing for the estimation of characteristics of the polymer coating: the brush length L, and the Brinkman length ξ, determined by its resistance to flows. We demonstrate that the Debye layer provides a convenient and faithful probe to the characterization of polymer coatings on particles. Because the method simply relies on a conventional zetameter, it is widely accessible and offers a practical tool to rapidly probe neutral polymer brushes, an asset in the development and utilization of polymer-coated colloidal particles.","lang":"eng"}],"_id":"9054","language":[{"iso":"eng"}],"scopus_import":"1","issue":"17","page":"4274-4282","status":"public","publication":"Soft Matter","date_updated":"2023-02-23T13:47:45Z","oa_version":"None","title":"Rapid characterization of neutral polymer brush with a conventional zetameter and a variable pinch of salt","date_created":"2021-02-01T13:45:11Z","keyword":["General Chemistry","Condensed Matter Physics"],"publication_identifier":{"issn":["1744-683X"],"eissn":["1744-6848"]},"publication_status":"published","pmid":1,"extern":"1","publisher":"Royal Society of Chemistry ","article_processing_charge":"No","month":"05","article_type":"original","volume":16,"author":[{"first_name":"Mena","last_name":"Youssef","full_name":"Youssef, Mena"},{"last_name":"Morin","full_name":"Morin, Alexandre","first_name":"Alexandre"},{"last_name":"Aubret","full_name":"Aubret, Antoine","first_name":"Antoine"},{"first_name":"Stefano","full_name":"Sacanna, Stefano","last_name":"Sacanna"},{"full_name":"Palacci, Jérémie A","last_name":"Palacci","first_name":"Jérémie A","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","orcid":"0000-0002-7253-9465"}],"doi":"10.1039/c9sm01850f"},{"publication_status":"published","oa_version":"None","date_created":"2021-02-02T13:30:50Z","title":"Ionic solids from common colloids","publication_identifier":{"eissn":["1476-4687"],"issn":["0028-0836"]},"keyword":["Multidisciplinary"],"article_type":"original","month":"04","volume":580,"author":[{"first_name":"Theodore","full_name":"Hueckel, Theodore","last_name":"Hueckel"},{"first_name":"Glen M.","last_name":"Hocky","full_name":"Hocky, Glen M."},{"last_name":"Palacci","full_name":"Palacci, Jérémie A","orcid":"0000-0002-7253-9465","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","first_name":"Jérémie A"},{"full_name":"Sacanna, Stefano","last_name":"Sacanna","first_name":"Stefano"}],"doi":"10.1038/s41586-020-2205-0","pmid":1,"extern":"1","publisher":"Springer Nature","article_processing_charge":"No","day":"23","citation":{"chicago":"Hueckel, Theodore, Glen M.

On the micrometre scale, however, colloids in water defy the intuitively simple idea of forming crystals from oppositely charged partners, instead forming non-equilibrium structures such as clusters and gels5-7. Although various systems have been engineered to grow binary crystals8-11, native surface charge in aqueous conditions has not been used to assemble crystalline materials. Here we form ionic colloidal crystals in water through an approach that we refer to as polymer-attenuated Coulombic self-assembly. The key to crystallization is the use of a neutral polymer to keep particles separated by well defined distances, allowing us to tune the attractive overlap of electrical double layers, directing particles to disperse, crystallize or become permanently fixed on demand. The nucleation and growth of macroscopic single crystals is demonstrated by using the Debye screening length to fine-tune assembly. Using a variety of colloidal particles and commercial polymers, ionic colloidal crystals isostructural to caesium chloride, sodium chloride, aluminium diboride and K4C60 are selected according to particle size ratios. Once fixed by simply diluting out solution salts, crystals are pulled out of the water for further manipulation, demonstrating an accurate translation from solution-phase assembly to dried solid structures. In contrast to other assembly approaches, in which particles must be carefully engineered to encode binding information12-18, polymer-attenuated Coulombic self-assembly enables conventional colloids to be used as model colloidal ions, primed for crystallization.

Microfluidic networks of closed pathways pose the challenge of determining the shortest exit pathway, which involves the proper local decision-making at each bifurcating junction. Here, we focus on the basic decision faced at a T-junction by a microscopic particle, which orients among possible paths via its sensing of a diffusible substance's concentration. We study experimentally the navigation of colloidal particles following concentration gradients by diffusiophoresis. We treat the situation as a mean first passage time (MFPT) problem that unveils the important role of a separatrix in the concentration field to determine the statistics of path taking. Further, we use numerical experiments to study different strategies, including biomimetic ones such as run and tumble or Markovian chemotactic migration. The discontinuity in the MFPT at the junction makes it remarkably difficult for microscopic agents to follow the shortest path, irrespective of adopted navigation strategy. In contrast, increasing the size of the sensing agents improves the efficiency of short-path taking by harvesting information on a larger scale. It inspires the development of a run-and-whirl dynamics that takes advantage of the mathematical properties of harmonic functions to emulate particles beyond their own size."}],"language":[{"iso":"eng"}],"type":"journal_article","quality_controlled":"1","date_published":"2020-10-14T00:00:00Z","article_number":"104202","intvolume":"         5","year":"2020","ddc":["530"],"user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","date_updated":"2023-02-23T13:50:55Z","publication":"Physical Review Fluids","file_date_updated":"2021-02-18T14:12:24Z","issue":"10","scopus_import":"1","status":"public","file":[{"relation":"main_file","file_id":"9163","date_updated":"2021-02-18T14:12:24Z","creator":"cziletti","file_name":"2020_PhysRevFluids_Gandhi.pdf","checksum":"dfecfadbd79fd760fb4db20d1e667f17","date_created":"2021-02-18T14:12:24Z","file_size":730504,"content_type":"application/pdf","success":1,"access_level":"open_access"}],"publication_status":"published","title":"Decision-making at a T-junction by gradient-sensing microscopic agents","date_created":"2021-02-18T14:07:16Z","oa_version":"Published Version","publication_identifier":{"issn":["2469-990X"]},"author":[{"first_name":"Tanvi","full_name":"Gandhi, Tanvi","last_name":"Gandhi"},{"last_name":"Mac Huang","full_name":"Mac Huang, Jinzi","first_name":"Jinzi"},{"full_name":"Aubret, Antoine","last_name":"Aubret","first_name":"Antoine"},{"first_name":"Yaocheng","full_name":"Li, Yaocheng","last_name":"Li"},{"first_name":"Sophie","last_name":"Ramananarivo","full_name":"Ramananarivo, Sophie"},{"last_name":"Vergassola","full_name":"Vergassola, Massimo","first_name":"Massimo"},{"full_name":"Palacci, Jérémie A","last_name":"Palacci","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","first_name":"Jérémie A","orcid":"0000-0002-7253-9465"}],"volume":5,"article_type":"original","month":"10","doi":"10.1103/physrevfluids.5.104202","oa":1,"extern":"1","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"article_processing_charge":"No","publisher":"American Physical Society"},{"publication":"New Journal of Physics","date_updated":"2021-02-18T14:57:39Z","file_date_updated":"2021-02-18T14:53:33Z","issue":"6","scopus_import":"1","status":"public","citation":{"chicago":"Speck, Thomas, Julien Tailleur, and Jérémie A Palacci. “Focus on Active Colloids and Nanoparticles.” <i>New Journal of Physics</i>.

We recently demonstrated the hierarchical self-assembly of phoretic microswimmers into self-spinning microgears and their synchronization by diffusiophoretic interactions [Aubret et al., Nat. Phys., 2018]. In this paper, we adopt a pedagogical approach and expose our strategy to control self-assembly and build machines using phoretic phenomena. We notably introduce Highly Inclined Laminated Optical sheets microscopy (HILO) to image and characterize anisotropic and dynamic diffusiophoretic interactions, which cannot be performed by conventional fluorescence microscopy. The dynamics of a (haematite) photocatalytic material immersed in (hydrogen peroxide) fuel under various illumination patterns is first described and quantitatively rationalized by a model of diffusiophoresis, the migration of a colloidal particle in a concentration gradient. It is further exploited to design phototactic microswimmers that direct towards the high intensity of light, as a result of the reorientation of the haematite in a light gradient. We finally show the assembly of self-spinning microgears from colloidal microswimmers and carefully characterize the interactions using HILO techniques. The results are compared with analytical and numerical predictions and agree quantitatively, stressing the important role played by concentration gradients induced by chemical activity to control and design interactions. Because the approach described hereby is generic, this works paves the way for the rational design of machines by controlling phoretic phenomena.","lang":"eng"}],"language":[{"iso":"eng"}],"day":"21","citation":{"ieee":"A.

At equilibrium, the structure is encoded through specific interactions2,3,4,5,6,7,8, at an unfavourable entropic cost for the system. An alternative approach, widely used by nature, uses energy input to bypass the entropy bottleneck and develop features otherwise impossible at equilibrium9. Dissipative building blocks that inject energy locally were made available by recent advances in colloidal science10,11 but have not been used to control self-assembly. Here we show the targeted formation of self-powered microgears from active particles and their autonomous synchronization into dynamical superstructures. We use a photoactive component that consumes fuel, haematite, to devise phototactic microswimmers that form self-spinning microgears following spatiotemporal light patterns. The gears are coupled via their chemical clouds by diffusiophoresis12 and constitute the elementary bricks of synchronized superstructures, which autonomously regulate their dynamics. The results are quantitatively rationalized on the basis of a stochastic description of diffusio-phoretic oscillators dynamically coupled by chemical gradients. Our findings harness non-equilibrium phoretic phenomena to program interactions and direct self-assembly with fidelity and specificity. It lays the groundwork for the autonomous construction of dynamical architectures and functional micro-machinery.","lang":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1810.01033","open_access":"1"}],"date_published":"2018-11-01T00:00:00Z","user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","year":"2018","intvolume":"        14"},{"publication_status":"published","quality_controlled":"1","type":"journal_article","_id":"9165","abstract":[{"text":"Advances in colloidal synthesis allow for the design of particles with controlled patches.

Recent efforts have focused on developing artificial systems that can mimic microorganisms, in particular their self-propulsion. We report on the design and characterization of synthetic self-propelled particles that migrate upstream, known as positive rheotaxis. This phenomenon results from a purely physical mechanism involving the interplay between the polarity of the particles and their alignment by a viscous torque. We show quantitative agreement between experimental data and a simple model of an overdamped Brownian pendulum. The model notably predicts the existence of a stagnation point in a diverging flow. We take advantage of this property to demonstrate that our active particles can sense and predictably organize in an imposed flow. Our colloidal system represents an important step toward the realization of biomimetic microsystems with the ability to sense and respond to environmental changes."}],"external_id":{"arxiv":["1505.05111"],"pmid":["26601175"]},"type":"journal_article","quality_controlled":"1","issue":"4","scopus_import":"1","status":"public","date_updated":"2023-02-23T13:47:52Z","publication":"Science Advances","file_date_updated":"2021-02-02T13:22:19Z","date_created":"2021-02-02T13:15:02Z","title":"Artificial rheotaxis","oa_version":"Published Version","publication_identifier":{"issn":["2375-2548"]},"arxiv":1,"file":[{"file_id":"9058","creator":"cziletti","date_updated":"2021-02-02T13:22:19Z","relation":"main_file","checksum":"b97d62433581875c1b85210c5f6ae370","file_name":"2015_ScienceAdvances_Palacci.pdf","content_type":"application/pdf","success":1,"file_size":2416780,"date_created":"2021-02-02T13:22:19Z","access_level":"open_access"}],"publication_status":"published","extern":"1","pmid":1,"tmp":{"image":"/images/cc_by_nc.png","short":"CC BY-NC (4.0)","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode"},"article_processing_charge":"No","publisher":"American Association for the Advancement of Science ","author":[{"orcid":"0000-0002-7253-9465","first_name":"Jérémie A","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","last_name":"Palacci","full_name":"Palacci, Jérémie A"},{"first_name":"Stefano","full_name":"Sacanna, Stefano","last_name":"Sacanna"},{"first_name":"Anaïs","last_name":"Abramian","full_name":"Abramian, Anaïs"},{"last_name":"Barral","full_name":"Barral, Jérémie","first_name":"Jérémie"},{"full_name":"Hanson, Kasey","last_name":"Hanson","first_name":"Kasey"},{"last_name":"Grosberg","full_name":"Grosberg, Alexander Y.","first_name":"Alexander Y."},{"first_name":"David J.","last_name":"Pine","full_name":"Pine, David J."},{"first_name":"Paul M.","full_name":"Chaikin, Paul M.","last_name":"Chaikin"}],"volume":1,"article_type":"original","month":"05","doi":"10.1126/sciadv.1400214","oa":1}]
