Self-powered therapeutic release from conducting polymer/graphene oxide films on magnesium

A SEM micrograph of the polymer graphene oxide dexamethasone containing film, mechanism of the corrosion driven drug release and the quantified drug release verifying corrosion being the driving force for drug release as no drug release from coatings on non-corroding gold sample, and increased drug release from coatings on Mg samples with larger Mg exposure.134
