Hierarchical construction of a mechanically stable peptide–graphene oxide hybrid hydrogel for drug delivery and pulsatile triggered release in vivo†
Abstract
The design of hydrogels with controllable drug-release properties remains challenging. Here we report a hydrogel made of hierarchical graphene oxide sheets and peptide assemblies for on-demand drug release. The hydrogel possesses high drug-sustainability and the release of drugs can be precisely and remotely controlled through external stimuli.
