Summary: A new strategy is proposed to decouple the deformation rate and deformation degree of self-shaping hydrogels, allowing for complex deformations from 2D to 3D to temporary 4D. By controlling the local gradients of photopolymerized gradient hydrogels, various controllable shape evolutions can be achieved.

Summary: A responsive photonic hydrogel was prepared by embedding a three-dimensional photonic crystal into an amino-functionalized hydrogel, enabling colorimetric detection of formaldehyde (FA). When the hydrogel reacts with FA, it undergoes volume shrinkage and a decrease in microsphere spacing, resulting in a blue shift in reflectance spectra and a color change from red to cyan. This photonic hydrogel shows high sensitivity, selectivity, and accuracy for detecting FA in air and aquatic products, providing a new approach for designing responsive photonic hydrogels for other target analytes.

Summary: Rotaxanes and molecular knots have unique properties due to the presence of a mechanical bond that interlocks the molecular components permanently. The disassembly of the interlocked structure can activate properties that are concealed in the parent compound. This study presents the development of stimuli-responsive Cu-I-complexed [2]catenanes as OFF/ON catalysts for the copper-catalyzed alkyne-azide cycloaddition (CuAAC) reaction.

Summary: An active flavonoid compound, rutin, was incorporated into a guanosine phenylborate hydrogel (GBR) for the treatment of inflammatory bowel disease (IBD). The hydrogel exhibited good stability and injectability, and achieved dual-responsive release in an acidic pH and excessive ROS-containing medium. In vivo studies showed that the GBR hydrogel had higher therapeutic efficacy than free rutin and could suppress the expression of inflammatory cytokines.
