3D Graphene Oxide–Polymer Hydrogel: Near‐Infrared Light‐Triggered Active Scaffold for Reversible Cell Capture and On‐Demand Release

Abstract

An active cell scaffold based on a graphene-polymer hydrogel has been successfully fabricated. The macroporous hydrogel can efficiently capture cells not only through the bioadhesive ligand RGD but also through on-demand release of cells with an NIR light stimulus. The latter process shows better dynamic control over cells than traditional passive-hydrogel-based cell depots.
