Inside Back Cover: Tough PEG-only hydrogels with complex 3D structure enabled by digital light processing of “all-PEG” resins

Abstract

Creating tough PEG hydrogels with complex 3D structure is a challenging task. We present a 3D printing method that offers precise production of these hydrogels, leveraging heat-assisted digital light processing and a unique dual-macromonomer “all-PEG” resin that includes a four-arm macrophotoinitiator. We fabricated porous hydrogel scaffolds resembling trabecular structures with good bioactivity, underscoring the promise of our approach in the realm of tissue regeneration (e368).
