Surface PEGylation of nanodiamond through a facile Michael addition reaction for intracellular drug delivery

Nanodiamond (ND) has been regarded as one of the most fascinating carbon nanomaterials for biomedical applications owing to its excellent physicochemical and biological properties. The biomedical application of ND-based materials mainly depends on its surface chemistry and properties, so the surface modification of ND is very important to improve its final biomedical application performance. In this work, a novel route for the surface...
