A three-dimensional graphene oxide supramolecular hydrogel for infrared light-responsive cascade release of two anticancer drugs†
Abstract
A three dimensional supramolecular hydrogel consisting of prodrug-modified graphene oxide and α-cyclodextrin was developed. This hydrogel with a well-ordered interior microstructure integrated hydrophobic and hydrophilic anticancer drugs into a single multifunctional platform, and underwent a gel–sol transition leading to cascade release of two drugs in an on-demand fashion upon NIR light irradiation.
