In this technique, conductance is continuously recorded as a metal point contact is broken in a solution of molecules. Conductance plateaus are seen when stable molecular junctions are formed. Typically, thousands of junctions are created and measured, yielding thousands of distinct conductance versus extension traces. However, such traces are rarely analyzed individually to recognize the types of junctions formed. Here, we present a deep learning-based method to identify molecular junctions and show that it performs better than several commonly used and recently reported techniques. We demonstrate molecular junction identification from mixed solution measurements with accuracies as high as 97%. We also apply this model to an in situ electric field-driven isomerization reaction of a [3]cumulene to follow the reaction over time. Furthermore, we demonstrate that our model can remain accurate even when a key parameter, the average junction conductance, is eliminated from the analysis, showing that our model goes beyond conventional analysis in existing methods."}],"publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"article_processing_charge":"No","volume":20,"quality_controlled":"1","article_type":"letter_note","pmid":1,"day":"03","author":[{"last_name":"Fu","first_name":"Tianren","full_name":"Fu, Tianren"},{"last_name":"Zang","full_name":"Zang, Yaping","first_name":"Yaping"},{"first_name":"Qi","full_name":"Zou, Qi","last_name":"Zou"},{"last_name":"Nuckolls","first_name":"Colin","full_name":"Nuckolls, Colin"},{"id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","last_name":"Venkataraman","orcid":"0000-0002-6957-6089","full_name":"Venkataraman, Latha","first_name":"Latha"}],"page":"3320-3325","date_published":"2020-04-03T00:00:00Z","date_created":"2024-09-09T07:20:52Z","issue":"5","type":"journal_article","intvolume":"        20","status":"public","extern":"1","year":"2020","publication":"Nano Letters","publication_status":"published","fulldoi":"https://doi.org/10.1021/acs.nanolett.0c00198"},{"volume":20,"OA_type":"closed access","article_type":"letter_note","pmid":1,"quality_controlled":"1","author":[{"first_name":"Suman","full_name":"Gunasekaran, Suman","last_name":"Gunasekaran"},{"last_name":"Greenwald","first_name":"Julia E.","full_name":"Greenwald, Julia E."},{"orcid":"0000-0002-6957-6089","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","last_name":"Venkataraman","full_name":"Venkataraman, Latha","first_name":"Latha"}],"day":"06","page":"2843-2848","date_created":"2024-09-09T07:36:41Z","date_published":"2020-03-06T00:00:00Z","intvolume":"        20","status":"public","year":"2020","extern":"1","issue":"4","type":"journal_article","publication_status":"published","fulldoi":"https://doi.org/10.1021/acs.nanolett.0c00605","publication":"Nano Letters","language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"03","scopus_import":"1","oa_version":"None","title":"Visualizing quantum interference in molecular junctions","publisher":"American Chemical Society","_id":"17913","date_updated":"2024-12-10T12:24:13Z","external_id":{"pmid":["32142291"]},"article_processing_charge":"No","citation":{"apa":"Gunasekaran, S., Greenwald, J.

The transmission function accounts for electrons tunneling through multiple molecular orbitals (MOs) with different phases, which gives rise to quantum interference (QI) effects. Because the transmission function comprises both interfering and noninterfering effects, individual interferences between MOs cannot be deduced from the transmission function directly. Herein, we demonstrate how the transmission function can be deconstructed into its constituent interfering and noninterfering contributions for any model molecular junction. These contributions are arranged in a matrix and displayed pictorially as a QI map, which allows one to easily identify individual QI effects. Importantly, we show that exponential conductance decay with increasing oligomer length is primarily due to an increase in destructive QI. With an ability to “see” QI effects using the QI map, we find that QI is vital to all molecular-scale electron transport."}]},{"doi":"10.1021/acs.nanolett.0c00136","citation":{"chicago":"Hernangómez-Pérez, Daniel, Suman Gunasekaran, Latha Venkataraman, and Ferdinand Evers. “Solitonics with Polyacetylenes.” <i>Nano Letters</i>.

From a fundamental perspective, there are two main reasons for the interest. First, polyacetylenes are a prime realization of a one-dimensional topological insulator. Second, long molecules support freely propagating topological domain-wall states, so-called “solitons,” which provide an early paradigm for spin-charge separation. Because of recent experimental developments, individual polyacetylene chains can now be synthesized on substrates. Motivated by this breakthrough, we here propose a novel way for chemically supported soliton design in these systems. We demonstrate how to control the soliton position and how to read it out via external means. Also, we show how extra soliton–antisoliton pairs arise when applying a moderate static electric field. We thus make a step toward functionality of electronic devices based on soliton manipulation, that is, “solitonics”."}],"publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"article_processing_charge":"No","external_id":{"pmid":["32125870"]},"publisher":"American Chemical Society","_id":"17914","date_updated":"2024-12-10T12:26:43Z","title":"Solitonics with polyacetylenes","oa_version":"None","scopus_import":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"03","language":[{"iso":"eng"}],"publication":"Nano Letters","publication_status":"published","fulldoi":"https://doi.org/10.1021/acs.nanolett.0c00136","issue":"4","type":"journal_article","intvolume":"        20","extern":"1","year":"2020","status":"public","date_published":"2020-03-03T00:00:00Z","date_created":"2024-09-09T07:38:36Z","page":"2615-2619","day":"03","author":[{"last_name":"Hernangómez-Pérez","full_name":"Hernangómez-Pérez, Daniel","first_name":"Daniel"},{"first_name":"Suman","full_name":"Gunasekaran, Suman","last_name":"Gunasekaran"},{"full_name":"Venkataraman, Latha","first_name":"Latha","last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","orcid":"0000-0002-6957-6089"},{"full_name":"Evers, Ferdinand","first_name":"Ferdinand","last_name":"Evers"}],"quality_controlled":"1","article_type":"letter_note","OA_type":"closed access","pmid":1,"volume":20},{"fulldoi":"https://doi.org/10.1021/acs.nanolett.9b04445","publication_status":"published","publication":"Nano Letters","date_created":"2019-12-10T15:36:05Z","date_published":"2020-01-08T00:00:00Z","oa":1,"status":"public","year":"2020","intvolume":"        20","related_material":{"record":[{"relation":"research_data","status":"public","id":"9726"},{"relation":"research_data","id":"9885","status":"public"}]},"type":"journal_article","issue":"1","isi":1,"author":[{"orcid":"0000-0003-0506-4217","id":"50B2A802-6007-11E9-A42B-EB23E6697425","last_name":"Ucar","full_name":"Ucar, Mehmet C","first_name":"Mehmet C"},{"last_name":"Lipowsky","full_name":"Lipowsky, Reinhard","first_name":"Reinhard"}],"day":"08","page":"669-676","volume":20,"pmid":1,"article_type":"letter_note","quality_controlled":"1","corr_author":"1","department":[{"_id":"EdHa"}],"article_processing_charge":"No","publication_identifier":{"issn":["1530-6984"],"eissn":["1530-6992"]},"abstract":[{"lang":"eng","text":"In the living cell, we encounter a large variety of motile processes such as organelle transport and cytoskeleton remodeling. These processes are driven by motor proteins that generate force by transducing chemical free energy into mechanical work. In many cases, the molecular motors work in teams to collectively generate larger forces. Recent optical trapping experiments on small teams of cytoskeletal motors indicated that the collectively generated force increases with the size of the motor team but that this increase depends on the motor type and on whether the motors are studied in vitro or in vivo. Here, we use the theory of stochastic processes to describe the motion of N motors in a stationary optical trap and to compute the N-dependence of the collectively generated forces. We consider six distinct motor types, two kinesins, two dyneins, and two myosins. We show that the force increases always linearly with N but with a prefactor that depends on the performance of the single motor. Surprisingly, this prefactor increases for weaker motors with a lower stall force. This counter-intuitive behavior reflects the increased probability with which stronger motors detach from the filament during strain generation. Our theoretical results are in quantitative agreement with experimental data on small teams of kinesin-1 motors."}],"citation":{"mla":"Ucar, Mehmet C., and Reinhard Lipowsky. “Collective Force Generation by Molecular Motors Is Determined by Strain-Induced Unbinding.” <i>Nano Letters</i>, vol. 20, no. 1, American Chemical Society, 2020, pp. 669–76, doi:<a href=\"https://doi.org/10.1021/acs.nanolett.9b04445\">10.1021/acs.nanolett.9b04445</a>.","apa":"Ucar, M.

To fulfill this potential, the interface between organic radicals and metal electrodes must be well characterized. Here, through a combined effort that includes synthesis, scanning tunneling microscopy, X-ray spectroscopy, and single-molecule conductance measurements, we comprehensively probe the electronic interaction between gold metal electrodes and a benchtop stable radical—the Blatter radical. We find that despite its open-shell character and having a half-filled orbital close to the Fermi level, the radical is stable on a gold substrate under ultrahigh vacuum. We observe a Kondo resonance arising from the radical and spectroscopic signatures of its half-filled orbitals. By contrast, in solution-based single-molecule conductance measurements, the radical character is lost through oxidation with charge transfer occurring from the molecule to metal. Our experiments show that the stability of radical states can be very sensitive to the environment around the molecule."}],"publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"citation":{"ieee":"J.

Here, we form Au–molecule–Au junctions using a custom scanning tunneling microscope and explore charge transport through current–voltage measurements. We focus on the resonant tunneling regime of two molecules, one that is primarily an electron conductor and one that conducts primarily holes. We find that in the high bias regime, junctions that do not rupture demonstrate reproducible and pronounced negative differential resistance (NDR)-like features followed by hysteresis with peak-to-valley ratios exceeding 100 in some cases. Furthermore, we show that both junction rupture and NDR are induced by charging of the molecular orbital dominating transport and find that the charging is reversible at lower bias and with time with kinetic time scales on the order of hundreds of milliseconds. We argue that these results cannot be explained by existing models of charge transport and likely require theoretical advances describing the transition from coherent to sequential tunneling. Our work also suggests new rules for operating single-molecule devices at high bias to obtain highly nonlinear behavior."}],"publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"03","language":[{"iso":"eng"}],"scopus_import":"1","oa_version":"None","date_created":"2024-09-09T07:46:01Z","date_published":"2019-03-01T00:00:00Z","intvolume":"        19","status":"public","extern":"1","year":"2019","issue":"4","type":"journal_article","publication_status":"published","fulldoi":"https://doi.org/10.1021/acs.nanolett.9b00316","publication":"Nano Letters","volume":19,"article_type":"original","OA_type":"closed access","pmid":1,"quality_controlled":"1","author":[{"last_name":"Fung","first_name":"E-Dean","full_name":"Fung, E-Dean"},{"first_name":"David","full_name":"Gelbwaser, David","last_name":"Gelbwaser"},{"first_name":"Jeffrey","full_name":"Taylor, Jeffrey","last_name":"Taylor"},{"full_name":"Low, Jonathan","first_name":"Jonathan","last_name":"Low"},{"last_name":"Xia","first_name":"Jianlong","full_name":"Xia, Jianlong"},{"full_name":"Davydenko, Iryna","first_name":"Iryna","last_name":"Davydenko"},{"last_name":"Campos","full_name":"Campos, Luis M.","first_name":"Luis M."},{"last_name":"Marder","first_name":"Seth","full_name":"Marder, Seth"},{"last_name":"Peskin","first_name":"Uri","full_name":"Peskin, Uri"},{"full_name":"Venkataraman, Latha","first_name":"Latha","last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","orcid":"0000-0002-6957-6089"}],"day":"01","page":"2555-2561"},{"external_id":{"pmid":["29461838"]},"date_updated":"2026-04-15T07:52:46Z","publisher":"American Chemical Society ","_id":"21523","title":"Single-layer metasurface with controllable multiwavelength functions","abstract":[{"lang":"eng","text":"In this paper, we report dispersion-engineered metasurfaces with distinct functionalities controlled by wavelength.

Most of these components do not bind the cargo. Here, we show that such “inert” components can be crucial for the precise control of cross-membrane trafficking. Using a statistical mechanics model and molecular dynamics simulations, we demonstrate that the presence of inert membrane components of small isotropic curvatures dramatically influences cargo endocytosis, even if the total spontaneous curvature of such a membrane remains unchanged. Curved lipids, such as cholesterol, as well as asymmetrically included proteins and tethered sugars can, therefore, actively participate in the control of the membrane trafficking of nanoscopic cargo. We find that even a low-level expression of curved inert membrane components can determine the membrane selectivity toward the cargo size and can be used to selectively target membranes of certain compositions. Our results suggest a robust and general method of controlling cargo trafficking by adjusting the membrane composition without needing to alter the concentration of receptors or the average membrane curvature. This study indicates that cells can prepare for any trafficking event by incorporating curved inert components in either of the membrane leaflets.","lang":"eng"}],"publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"citation":{"chicago":"Curk, Tine, Peter Wirnsberger, Jure Dobnikar, Daan Frenkel, and Anđela Šarić. “Controlling Cargo Trafficking in Multicomponent Membranes.” <i>Nano Letters</i>.

Herein, we perform scanning tunneling microscope based break-junction measurements on a series of three cyanine dyes of increasing length. We demonstrate, at the single molecule level, that these short chain polymethine systems exhibit a substantially smaller decay in conductance with length (attenuation factor β = 0.04 Å–1) compared to traditional polyenes (β ≈ 0.2 Å–1). Furthermore, we show that by changing solvent we are able to shift the β value, demonstrating a remarkable negative β value, with conductance increasing with molecular length. First principle calculations provide support for the experimentally observed near-uniform length dependent conductance and further suggest that the variations in β with solvent are due to solvent-induced changes in the alignment of the frontier molecular orbitals relative to the Fermi energy of the leads. A simplified Hückel model suggests that the smaller decay in conductance correlates with the smaller degree of bond order alternation present in polymethine compounds compared to polyenes. These findings may enable the design of molecular wires without a length-dependent decay for efficient electron transport at the nanoscale.","lang":"eng"}],"publication_identifier":{"issn":["1530-6984"],"eissn":["1530-6992"]},"_id":"17929","publisher":"American Chemical Society","date_updated":"2024-12-11T08:39:06Z","external_id":{"pmid":["30187756"]},"title":"Near length-independent conductance in polymethine molecular wires"},{"volume":17,"article_type":"letter_note","OA_type":"closed access","pmid":1,"quality_controlled":"1","author":[{"first_name":"Anders","full_name":"Borges, Anders","last_name":"Borges"},{"full_name":"Xia, Jianlong","first_name":"Jianlong","last_name":"Xia"},{"full_name":"Liu, Sheng Hua","first_name":"Sheng Hua","last_name":"Liu"},{"last_name":"Venkataraman","orcid":"0000-0002-6957-6089","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","first_name":"Latha","full_name":"Venkataraman, Latha"},{"last_name":"Solomon","full_name":"Solomon, Gemma C.","first_name":"Gemma C."}],"day":"26","page":"4436-4442","date_created":"2024-09-09T08:50:14Z","date_published":"2017-06-26T00:00:00Z","intvolume":"        17","status":"public","extern":"1","year":"2017","issue":"7","type":"journal_article","publication_status":"published","fulldoi":"https://doi.org/10.1021/acs.nanolett.7b01592","publication":"Nano Letters","month":"06","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"scopus_import":"1","oa_version":"None","title":"The role of through-space interactions in modulating constructive and destructive interference effects in benzene","publisher":"American Chemical Society","_id":"17942","date_updated":"2024-12-18T07:32:14Z","external_id":{"pmid":["28650176"]},"article_processing_charge":"No","doi":"10.1021/acs.nanolett.7b01592","citation":{"ista":"Borges A, Xia J, Liu SH, Venkataraman L, Solomon GC. 2017.

As a peculiarity, this allows a meta-coupled benzene molecule to exhibit higher conductance than a para-coupled benzene.

Using 4,4′-bipyridine bound to Au electrodes as a prototypical single-molecule junction, we report a 20–40% enhancement in conductance under illumination with 980 nm wavelength radiation. We probe the effects of subtle changes in the transmission function on light-enhanced current and show that discrete variations in the binding geometry result in a 10% change in enhancement. Importantly, we prove theoretically that the steady-state behavior of photon-assisted transport and hot-electron transport is identical but that hot-electron transport is the dominant mechanism for optically induced conductance enhancement in single-molecule junctions when the wavelength used is absorbed by the electrodes and the hot-electron relaxation time is long. We confirm this experimentally by performing polarization-dependent conductance measurements of illuminated 4,4′-bipyridine junctions. Finally, we perform lock-in type measurements of optical current and conclude that currents due to laser-induced thermal expansion mask optical currents.

Here, we present a new and simple technique for measuring the transmission functions of molecular junctions in the coherent tunneling limit, over an energy range of 1.5 eV around the Fermi energy. We create molecular junctions in an ionic environment with electrodes having different exposed areas, which results in the formation of electric double layers of dissimilar density on the two electrodes. This allows us to electrostatically shift the molecular resonance relative to the junction Fermi levels in a manner that depends on the sign of the applied bias, enabling us to map out the junction’s transmission function and determine the dominant orbital for charge transport in the molecular junction. We demonstrate this technique using two groups of molecules: one group having molecular resonance energies relatively far from EF and one group having molecular resonance energies within the accessible bias window. Our results compare well with previous electrochemical gating data and with transmission functions computed from first principles. Furthermore, with the second group of molecules, we are able to examine the behavior of a molecular junction as a resonance shifts into the bias window.

Here, we present a method for the efficient production of M13 bacteriophage-derived genomic DNA using high-cell-density fermentation of Escherichia coli in stirred-tank bioreactors. We achieve phage titers of up to 1.6 × 1014 plaque-forming units per mL.
