Nanodiamonds as vehicles for systemic and localized drug delivery

Abstract

Owing to their exceptional biocompatibility and unique surface properties, nanodiamonds (NDs) are shown to be a progressively promising nanomaterial for drug delivery. In this article, NDs as a platform for a host of biomedical applications are described, with an emphasis on cancer therapy, ranging from systemic modalities to primary constituents within polymer hybrid microfilms. Experimental results and theoretical explanations of ND–drug dynamics are compared. Water-dispersion of previously insoluble therapeutics when complexed with NDs demonstrates great promise in expanding current drug delivery options. Various forms of incorporating NDs within microfilms as a localized drug release coating and implant are also discussed.
