A Critical Review on the Evolution of Chitosan‐Based Injectable Hydrogels in Bone Regeneration

Advanced Materials Interfaces, EarlyView.
The graphical illustration depicts hydrogel formulation using chitosan and biocompatible cross‐linkers, major advantages, and incorporation of cells, osteoinductive factors, and therapeutic drugs. Following injection, pH‐responsive gelation enables controlled drug release, promotes cell recruitment and osteogenic differentiation, enhances extracellular

Bioelectrochemically Powered Out-of-Equilibrium Hydrogels Enable Feedback-Regulated Functions. [PDF]

Adv Sci (Weinh)
A bioelectrochemically powered hydrogel operates far from equilibrium via an antagonistic redox cycle that regulates disulfide exchange within a polyrotaxane network. Coupling electrochemical mediator cycling with enzymatic feedback enables dynamic control of hydrogel mechanics and transport properties, driving glucose‐responsive insulin release with ...

Region‐Specific Profiling of the Gut Microbiome and Metabolite Landscape in Response to Dietary Intervention Using Electronics‐Free Ingestible Smart Sampling Capsules

Advanced Materials Technologies, EarlyView.
Region‐specific profiling of the gut microbiome is achieved non‐invasively using electronics‐free ingestible sampling capsules that activate at defined intestinal sites through stimuli‐responsive coatings. Deployed in a porcine dietary intervention model, the capsules resolve spatially distinct, fiber‐driven shifts in microbial composition and short ...
