Engineering Multilayer Poly(ethylene glycol) Hydrogels via Off-Stoichiometry Thiol–Ene Chemistry
Multilayer hydrogels with spatially controllable mechanical and functional properties are increasingly valuable, yet their utility is often constrained by fabrication challenges such as weak interfacial adhesion as well as reliance on cytotoxic photoinitiators and UV exposure. This study presents a simple, robust, and...
