Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

Advanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

Directed Functionalization of Recombinant Spider Silk Nonwoven Membranes with Antibodies Using Non‐Canonical Amino Acids

Advanced Materials, EarlyView.
A recombinant spider silk protein was functionalized by incorporating genetically encoded bio‐orthogonal reactive azido‐groups. The azido‐functionalized proteins were produced in a scalable biotechnological process, and particles, films, as well as nanofibers were established as anchorage for fully functional antibodies via site‐specific bio‐orthogonal

Efficient Non‐Invasive Rejuvenation of Spent Lithium Iron Phosphate Batteries Through Controlled Overdischarge

Advanced Materials, EarlyView.
This strategy rejuvenates spent lithium iron phosphate battery by non‐invasively targeting Li+ trapped within the solid‐electrolyte interphase (SEI). This method mitigates copper dissolution and reduces Li/Fe antisite defects, achieving 9.56% capacity recovery and 214 cycles lifespan extension. The process requires only 3 MJ kg−1 of energy and emitting
