Intrinsic Anti‐Freezing, Tough, and Transparent Hydrogels for Smart Optical and Multi‐Modal Sensing Applications

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 8, 2025

Abstract Hydrogels have received great attention due to their molecular designability and wide application range. However, they are prone freeze at low temperatures the existence of mass water molecules, which can damage flexibility transparency, greatly limiting use in cold environments. Although adding cryoprotectants reduce freezing point hydrogels, it may also deteriorate mechanical properties face risk cryoprotectant leakage. Herein, microphase‐separated structures hydrogels regulated confine molecules sub‐6 nm nanochannels increase proportion bound water, endowing with intrinsic anti‐freezing properties, high strength, good stretchability, remarkable fracture energy, puncture resistance. Even after being kept liquid nitrogen for 1000 h, hydrogel still maintains transparency. The exhibit excellent low‐temperature shape memory intelligent optical waveguide properties. Additionally, be assembled into strain pressure sensors flexible sensing both room temperatures. intrinsically offers broad prospects electronic applications.

Tailorable biosensors for real-time monitoring of stress distribution in soft biomaterials and living tissues

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Jan. 27, 2025

Visualizing mechanical stress distribution in soft and live biomaterials is essential for understanding biological processes improving material design. However, it remains challenging due to their complexity, dynamic nature, sensitivity requirements, necessitating innovative techniques. Since polysaccharides are common various biomaterials, a biosensor integrating Förster resonance energy transfer (FRET)-based tension sensor module carbohydrate-binding modules (FTSM-CBM) has been designed real-time monitoring of the these biomaterials. By simple dripping or soaking, FTSM-CBM enables fast, reproducible semiquantitative detection both 2D 3D distributions polysaccharide-based hydrogels. Additionally, provides valuable information such as microstructure hints fracture site warnings. can also monitor locomotion maggots, which not feasible with most existing Furthermore, by changing CBM, be expanded This study powerful tool that may promote related research life materials science. key understand improve Here, authors design visualize living tissues.
