Nanodiamonds as vehicles for systemic and localized drug delivery.

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.
