Abstract

Here we present a simple physical method to produce magnetic nanodiamonds (NDs) using high dose Fe ion-implantation. The Fe atoms are distributed inside the NDs without affecting their crystal structure. So the NDs can be still functionalized through surface modification for targeted chemotherapy and the added magnetic property will make the NDs suitable for localized thermal treatment for cancer cells without the toxicity from the Fe atoms being directly in contact with the living tissue.
