Photoresponsive biomaterials have garnered increasing attention recently due to their ability dynamically regulate biological interactions and cellular behaviors in response light. This review provides an overview of recent advances the design, synthesis, applications photoresponsive biomaterials, including photochromic molecules, photocleavable linkers, photoreactive polymers. We highlight various approaches used control behavior these materials, modulation light intensity, wavelength, duration. Additionally, we discuss fields, drug delivery, tissue engineering, biosensing, optical storage. A selection significant cutting-edge articles collected years has been discussed based on structural pattern light-responsive performance, focusing mainly photoactivity azobenzene, hydrazone, diarylethenes, spiropyrans, design smart materials as most targeted desirable application. Overall, this highlights potential enable spatiotemporal processes opens up exciting opportunities for developing advanced with enhanced functionality.

Stimuli-responsive nanomaterials have attracted substantial interest in cancer therapy, as they hold promise to deliver anticancer agents tumor sites a precise and on-demand manner. Interestingly, supramolecular chemistry is burgeoning discipline that entails the reversible bonding between components at molecular nanoscale levels, recent advances this area offer possibility design nanotherapeutics with improved controllability functionality for therapy. Herein, we provide comprehensive summary of typical non-covalent interaction modes, which primarily include hydrophobic interaction, hydrogel bonding, host-guest π-π stacking, electrostatic interaction. Special emphasis placed on implications these modes novel stimuli-responsive drug delivery principles concepts, aiming enhance spatial, temporal, dosage precision cells. Finally, future perspectives are discussed highlight current challenges opportunities self-assembly-based nanotechnologies

An ultrawide-range photochromic molecular fluorescence emitter

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: June 26, 2024

Abstract Photocontrollable luminescent molecular switches capable of changing emitting color have been regarded as the ideal integration between intelligent and materials. A remaining challenge is to combine good luminescence properties with wide range wavelength transformation, especially when confined in a single system that forms well-defined nanostructures. Here, we report π-expanded photochromic photoswitch, which allows for comprehensive achievements including emission variation (240 nm wide, 400–640 nm), high photoisomerization extent (95%), pure (<100 full width at half maximum). We take advantageous mechanism modulating self-assembly intramolecular charge transfer synthesis construction, further realize by simple photocontrol. Based on this, both photoactivated anti-counterfeiting function self-erasing photowriting films are achieved fluorescence. This work will provide insight into design optical

Abstract Photoinduced transitions between the solid, glass, and liquid states based on molecular photoswitches promise a wide variety of applications. Photoswitchable adhesives are representative examples expected to contribute material recycling for sustainable future in era composite materials due strong bonding on-demand photo-induced debonding with minimal damage adherends. Only few known undergo these transitions, but recent progress, mainly azobenzene, has been remarkable. Here, we review photoinduced small molecules polymers over approximately decade systematically discuss designs, mechanisms, applications, merits demerits, challenges each photoswitch whole field. We hope this provides useful information, inspiration, ideas development field expansion its
