Nanodiamond (IMAGE) National University of Singapore Caption This is a schematic model showing surface and chemical structure of nanodiamond (ND) and Epirubicin (Epi), synthesis and aggregation of Epirubicin-ND complex (EPND). ND represented in truncated octahedron structure with different surface charge denoted with color. ND surface functional group indicated, including benzene ring, carboxyl group and hydrogen group. Molecular skeleton representing carbon, oxygen and Nitrogen atoms in Epi molecule was shown in red.
