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.
