Graphene oxide (GO) has been developed to be a nanocarrier of anti-cancer drugs due to its large surface area and biocompatibility; however, understanding of the interface chemistry is very limited. In this work, we report efficient loading and controlled release of doxorubicin (DOX) using the tunable surface of GO. A deep understanding of the surface chemistry between GO and DOX is achieved using spectroscopies and atomic force microscopy. Hydrogen bonding and π-π stacking are confirmed to be the non-covalent interactions between the drugs and the carriers. As a result, improvement of DOX delivery from the GO surface can be achieved using vitamin C.
