A Multifunctional Hydrogel Delivers Gold Compound and Inhibits Human Lung Cancer Xenograft

Purpose Interpenetrating network system (IPN), consisting of polyethylene glycol (PEG) –diacrylate (PEGdA) and modified gelatin, is a biocompatible and biodegradable hydrogel and has been studied for the local delivery of bioactive molecules and drugs. Gold(III) porphyrin(AuP) is a stable metal compound in the development for anticancer application when administered systemically. The aim of this work is to develop a novel formulation for AuP based on IPN for local delivery.
