However, it remains challenging to design physiologically stable self-assembling systems that demonstrate tunable and predictable behavior. Here, the use of zwitterionic tetrapeptide modalities to direct nanoparticle assembly under physiological conditions is reported. The self-assembly of gold nanoparticles can be activated by enzymatic unveiling of surface-bound zwitterionic tetrapeptides through matrix metalloprotease-9 (MMP-9), which is overexpressed by cancer cells. This robust nanoparticle assembly is achieved by multivalent, self-complementary interactions of the zwitterionic tetrapeptides. In cancer cells that overexpress MMP-9, the nanoparticle assembly process occurs near the cell membrane and causes size-induced selection of cellular uptake mechanism, resulting in diminished cell growth. The enzyme responsiveness, and therefore, indirectly, the uptake route of the system can be programmed by customizing the peptide sequence: a simple inversion of the two amino acids at the cleavage site completely inactivates the enzyme responsiveness, self-assembly, and consequently changes the endocytic pathway. This robust self-complementary, zwitterionic peptide design demonstrates the use of enzyme-activated electrostatic side-chain patterns as powerful and customizable peptide modalities to program nanoparticle self-assembly and alter cellular response in biological context.","lang":"eng"}],"quality_controlled":"1","status":"public","issue":"1","publisher":"Wiley","doi":"10.1002/adma.202104962","citation":{"mla":"Huang, Richard H., et al. “Self‐complementary Zwitterionic Peptides Direct Nanoparticle Assembly and Enable Enzymatic Selection of Endocytic Pathways.” <i>Advanced Materials</i>, vol. 34, no. 1, 2104962, Wiley, 2022, doi:<a href=\"https://doi.org/10.1002/adma.202104962\">10.1002/adma.202104962</a>.","ama":"Huang RH, Nayeem N, He Y, et al.

However, biological macromolecules such as DNA and proteins are naturally chiral, and thus the limited range of chiral space groups available hampers the crystallization of such molecules. Inspiring work over the past 15 years has shown that racemic mixtures of proteins, which were made possible by impressive advances in protein chemical synthesis, can indeed improve the success rate of protein crystallization experiments. More recently, the racemic crystallization approach was extended to include nucleic acids as a possible aid in the determination of enantiopure DNA crystal structures. Here, findings are reported that suggest that the benefits may extend beyond this. Two racemic crystal structures of the DNA sequence d(CCCGGG) are described which were found to fold into A-form DNA. This form differs from the Z-form DNA conformation adopted by the chiral equivalent in the solid state, suggesting that the use of racemates may also favour the emergence of new conformations. Importantly, the racemic mixture forms interactions in the solid state that differ from the chiral equivalent (including the formation of racemic pseudo-helices), suggesting that the use of racemic DNA mixtures could provide new possibilities for the design of precise self-assembled nanomaterials and nanostructures."}],"title":"Racemic crystal structures of A-DNA duplexes","publisher":"International Union of Crystallography","issue":"6","status":"public","quality_controlled":"1","OA_type":"hybrid","doi":"10.1107/s2059798322003928","tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"volume":78,"year":"2022","citation":{"apa":"Mandal, P.

Here, we propose a framework for the inverse design of multilayer metaoptics via topology optimization, showing that even few-wavelength thick devices can achieve high-efficiency multifunctionality, such as multiangle light concentration and plan-achromaticity. We embody our framework in multiple closely spaced patterned layers of a low-index polymer, with fabrication constraints specific to this platform enforced in the optimization process. We experimentally demonstrate our approach with an inverse-designed 3D-printed light concentrator working at five different nonparaxial angles of incidence. Our framework paves the way toward realizing multifunctional ultracompact 3D nanophotonic devices."}],"citation":{"mla":"Roques-Carmes, Charles, et al. “Toward 3D-Printed Inverse-Designed Metaoptics.” <i>ACS Photonics</i>, vol. 9, no. 1, American Chemical Society, 2022, pp. 43–51, doi:<a href=\"https://doi.org/10.1021/acsphotonics.1c01442\">10.1021/acsphotonics.1c01442</a>.","ama":"Roques-Carmes C, Lin Z, Christiansen RE, et al.

Scintillation has widespread applications in medical imaging, x-ray nondestructive inspection, electron microscopy, and high-energy particle detectors. Most research focuses on finding materials with brighter, faster, and more controlled scintillation. We developed a unified theory of nanophotonic scintillators that accounts for the key aspects of scintillation: energy loss by high-energy particles, and light emission by non-equilibrium electrons in nanostructured optical systems. We then devised an approach based on integrating nanophotonic structures into scintillators to enhance their emission, obtaining nearly an order-of-magnitude enhancement in both electron-induced and x-ray–induced scintillation. Our framework should enable the development of a new class of brighter, faster, and higher-resolution scintillators with tailored and optimized performance."}],"title":"A framework for scintillation in nanophotonics","publisher":"American Association for the Advancement of Science","issue":"6583","status":"public","quality_controlled":"1","fulldoi":"https://doi.org/10.1126/science.abm9293","language":[{"iso":"eng"}],"arxiv":1,"external_id":{"arxiv":["2110.11492"]},"date_published":"2022-02-25T00:00:00Z","author":[{"full_name":"Roques-Carmes, Charles","first_name":"Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","last_name":"Roques-Carmes"},{"first_name":"Nicholas","full_name":"Rivera, Nicholas","last_name":"Rivera"},{"first_name":"Ali","full_name":"Ghorashi, Ali","last_name":"Ghorashi"},{"first_name":"Steven E.","full_name":"Kooi, Steven E.","last_name":"Kooi"},{"last_name":"Yang","full_name":"Yang, Yi","first_name":"Yi"},{"last_name":"Lin","first_name":"Zin","full_name":"Lin, Zin"},{"last_name":"Beroz","full_name":"Beroz, Justin","first_name":"Justin"},{"first_name":"Aviram","full_name":"Massuda, Aviram","last_name":"Massuda"},{"last_name":"Sloan","full_name":"Sloan, Jamison","first_name":"Jamison"},{"first_name":"Nicolas","full_name":"Romeo, Nicolas","last_name":"Romeo"},{"last_name":"Yu","first_name":"Yang","full_name":"Yu, Yang"},{"last_name":"Joannopoulos","first_name":"John D.","full_name":"Joannopoulos, John D."},{"last_name":"Kaminer","full_name":"Kaminer, Ido","first_name":"Ido"},{"first_name":"Steven G.","full_name":"Johnson, Steven G.","last_name":"Johnson"},{"full_name":"Soljačić, Marin","first_name":"Marin","last_name":"Soljačić"}],"publication_identifier":{"issn":["0036-8075"],"eissn":["1095-9203"]},"scopus_import":"1","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2110.11492","open_access":"1"}],"article_number":"837","article_processing_charge":"No","type":"journal_article","day":"25"},{"date_published":"2022-06-01T00:00:00Z","oa_version":"None","publication":"Conference on Lasers and Electro-Optics","date_updated":"2026-05-04T12:54:57Z","language":[{"iso":"eng"}],"date_created":"2026-03-30T12:22:48Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","conference":{"start_date":"2022-05-15","location":"San Jose, CA, United States","name":"CLEO: Applications and Technology","end_date":"2022-05-20"},"extern":"1","_id":"21590","fulldoi":"https://doi.org/10.1364/cleo_at.2022.jw5q.1","month":"06","quality_controlled":"1","publisher":"Optica Publishing Group","day":"01","status":"public","type":"conference","title":"End-to-end nanophotonics inverse design for computational imaging","abstract":[{"text":"We introduce end-to-end inverse design in which a nanophotonics frontend is optimized in conjunction with a computational-imaging backend to minimize reconstruction errors.

Unlike diffractive optics, we show that subwavelength-scale “metasurface” designs can easily distinguish similar wavelength and polarization inputs. The proposed technique integrates a single-layer metasurface frontend with an efficient Tikhonov reconstruction backend, without any additional optics except a grayscale sensor. Our method yields multi-channel imaging by spontaneous demultiplexing: the metaoptics front-end separates different channels into distinct spatial domains whose locations on the sensor are optimally discovered by the inverse-design algorithm. We present large-area metasurface designs, compatible with standard lithography, for multi-spectral imaging, depth-spectral imaging, and “all-in-one” spectro-polarimetric-depth imaging with robust reconstruction performance (≲ 10% error with 1% detector noise). In contrast to neural networks, our framework is physically interpretable and does not require large training sets. It can be used to reconstruct arbitrary three-dimensional scenes with full multi-wavelength spectra and polarization textures.","lang":"eng"}],"title":"End-to-end metasurface inverse design for single-shot multi-channel imaging","date_created":"2026-03-30T12:22:48Z","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","article_type":"original","extern":"1","_id":"21638","DOAJ_listed":"1","month":"07","oa_version":"Published Version","publication":"Optics Express","intvolume":"        30","date_updated":"2026-04-27T09:09:05Z","oa":1,"page":"28358-28370","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1364/OE.449985"}],"publication_identifier":{"eissn":["1094-4087"]},"scopus_import":"1","author":[{"full_name":"Lin, Zin","first_name":"Zin","last_name":"Lin"},{"full_name":"Pestourie, Raphaël","first_name":"Raphaël","last_name":"Pestourie"},{"last_name":"Roques-Carmes","first_name":"Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","full_name":"Roques-Carmes, Charles"},{"full_name":"Li, Zhaoyi","first_name":"Zhaoyi","last_name":"Li"},{"last_name":"Capasso","first_name":"Federico","full_name":"Capasso, Federico"},{"full_name":"Soljačić, Marin","first_name":"Marin","last_name":"Soljačić"},{"full_name":"Johnson, Steven G.","first_name":"Steven G.","last_name":"Johnson"}],"day":"19","type":"journal_article","article_processing_charge":"No","ddc":["530"],"fulldoi":"https://doi.org/10.1364/oe.449985","external_id":{"pmid":[" 36299033"],"arxiv":["2111.01071"]},"pmid":1,"date_published":"2022-07-19T00:00:00Z","arxiv":1,"language":[{"iso":"eng"}]},{"abstract":[{"lang":"eng","text":"When impinging on optical structures or passing in their vicinity, free electrons can spontaneously emit electromagnetic radiation, a phenomenon generally known as cathodoluminescence. Free-electron radiation comes in many guises: Cherenkov, transition, and Smith-Purcell radiation, but also electron scintillation, commonly referred to as incoherent cathodoluminescence. While those effects have been at the heart of many fundamental discoveries and technological developments in high-energy physics in the past century, their recent demonstration in photonic and nanophotonic systems has attracted a lot of attention. Those developments arose from predictions that exploit nanophotonics for novel radiation regimes, now becoming accessible thanks to advances in nanofabrication. In general, the proper design of nanophotonic structures can enable shaping, control, and enhancement of free-electron radiation, for any of the above-mentioned effects. Free-electron radiation in nanophotonics opens the way to promising applications, such as widely-tunable integrated light sources from x-ray to THz frequencies, miniaturized particle accelerators, and highly sensitive high-energy particle detectors. Here, we review the emerging field of free-electron radiation in nanophotonics. We first present a general, unified framework to describe free-electron light-matter interaction in arbitrary nanophotonic systems. We then show how this framework sheds light on the physical underpinnings of many methods in the field used to control and enhance free-electron radiation. Namely, the framework points to the central role played by the photonic eigenmodes in controlling the output properties of free-electron radiation (e.g., frequency, directionality, and polarization).

Herein, we present a strategy to access three independent states (linear, cyclic keto, and cyclic enolate) of crown ether (CE)-substituted donor–acceptor Stenhouse adducts (DASAs) by limiting the tautomerization of the closed isomers. The linear–cyclic keto isomerization is reversibly triggered by treatment with metal ions (Na+ or K+) and CE, while the linear–cyclic enolate isomerization is induced by green light and heat. Density functional theory and molecular dynamics calculation results suggest that the steric effect and supramolecular interaction between the electron-donating and electron-withdrawing moieties play an important role in hindering the tautomerization between cyclic keto and cyclic enolate DASA-CE.

However, moving beyond simple binary responses necessitates the introduction of new elements that control the chemistry of the photoswitching process at the molecular scale. To achieve this goal, we designed, synthesized and developed a single photochrome, based on a modified donor–acceptor Stenhouse adduct (DASA), capable of independently addressing multiple molecular states. The multi-stage photoswitch enables complex switching phenomena. To demonstrate this, we show spatial control of the transformation of a three-stage photoswitch by tuning the population of intermediates along the multi-step reaction pathway of the DASAs without interfering with either the first or final stage. This allows for a photonic three-stage logic gate where the secondary wavelength solely negates the input of the primary wavelength. These results provide a new strategy to move beyond traditional on/off binary photochromic systems and enable the design of future molecular logic systems."}],"title":"A multi-stage single photochrome system for controlled photoswitching responses","publisher":"Springer Nature","status":"public","quality_controlled":"1","fulldoi":"https://doi.org/10.1038/s41557-022-00947-8","ddc":["540"],"language":[{"iso":"eng"}],"date_published":"2022-06-09T00:00:00Z","external_id":{"pmid":["35681046"]},"pmid":1,"author":[{"first_name":"Friedrich J","id":"7aca2cfc-46cf-11f0-abd3-8c96b5186745","full_name":"Stricker, Friedrich J","last_name":"Stricker"},{"full_name":"Sanchez, David M.","first_name":"David M.","last_name":"Sanchez"},{"first_name":"Umberto","full_name":"Raucci, Umberto","last_name":"Raucci"},{"full_name":"Dolinski, Neil D.","first_name":"Neil D.","last_name":"Dolinski"},{"last_name":"Zayas","first_name":"Manuel S.","full_name":"Zayas, Manuel S."},{"full_name":"Meisner, Jan","first_name":"Jan","last_name":"Meisner"},{"last_name":"Hawker","full_name":"Hawker, Craig.

Using a modular Diels−Alder “click” platform, we designed polymeric materials with varying DASA incorporation and investigated the relationships between the material composition and the resulting physical, mechanical, and photoswitching properties. We demonstrate that increasing the DASA concentration in polymer conjugates has a dramatic effect on the material’s physical and mechanical properties, such as the glass transition temperature (Tg) and elastic modulus, as well as the photoswitching properties, which are found to be highly dependent on Tg. We establish using a simple photoresponsive bilayer that actuation performance is controlled by the bilayer stiffness rather than the photochrome incorporation of DASA. Finally, we report and compare the light-induced property changes in Tg and the elastic modulus between the materials comprising the open or closed forms of DASAs. Our results demonstrate the importance of designing a material that is stiff enough to provide the mechanical strength required for actuation under load, but soft enough to reversibly switch at the operational temperature and provide key considerations for the development of application-geared photoswitchable materials.","lang":"eng"}],"issue":"1","status":"public","publisher":"American Chemical Society","quality_controlled":"1","OA_type":"closed access","doi":"10.1021/acsapm.1c01108","volume":4,"year":"2022","publication_status":"published","citation":{"ieee":"M.
