Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Traceless Photopolymerization with Non‐Pulsed Red Light Enables 3D‐Printable Cell‐Laden Hydrogels

open access: yesAdvanced Materials, EarlyView.
The paper presents a red‐light‐induced polymerization process, initiated by the FDA‐approved dye methylene blue and the cytocompatible co‐initiator triethanolamine, for fabricating hydrogels. This photopolymerization process is oxygen‐tolerant, cytocompatible, and, most importantly, leaves no color traces, resulting in completely transparent scaffolds.

A Photonastic Prototissue Capable of Photo‐Mechano‐Chemical Transduction

open access: yesAdvanced Materials, EarlyView.
Mimicking energy transduction in prototissue assemblies remains a challenge of bottom‐up synthetic biology. In this work, prototissues integrating protocells with photothermal gold nanoparticle proto‐organelles and a thermoresponsive polymeric proto‐cortex are developed.

Sonodynamic and Bioorthogonal Sonocatalytic Thrombotic Therapy Based on AIE Cationic Tetranuclear Ir(III) Complex Nanoplatform Guided by NIR‐Chemiluminescence Imaging

open access: yesAdvanced Materials, EarlyView.
AIE‐active tetranuclear Ir(III) complex Ir‐4 as a sonosensitizer/sonocatalyst is formulated into a nanoplatform with an H2S donor. Ir‐4@S‐R NPs achieves combined endogenous NIR chemiluminescence imaging, sonodynamic therapy and release of H2S in situ by a bioorthogonal sonocatalytic reaction in vivo, achieving safe thrombolysis and anti‐inflammatory ...

Granular Hydrogels as Brittle Yield Stress Fluids

open access: yesAdvanced Materials, EarlyView.
This work reports the Kamani‐Donley‐Rogers yield stress fluid model can describe granular hydrogel deformation. The model robustly captures transient rheology and self‐healing behavior for granular gels of varying composition using only six parameters. This framework provides new insight regarding the effect of material parameters on granular yielding ...
