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 ...
