Bio-inspired Polydopamine Surface Modification of Nanodiamonds and Its Reduction of Silver Nanoparticles

This method can help answer key questions about effective surface functionalization of nanodiamond, which have broad applications in material science and biomedicine. This method can be used for nanodiamonds. It can also be applied for other materials, such as metal nanoparticles, magnetic nanoparticles, or surfaces that need an active biopolymer coating.

In this method, nanodiamonds are funtionalized with a coating of polydopamine, a universal adhesive. The thickness of the PDA layer is well controlled by varying the concentration of dopamine. To begin, dissolve 30.29 grams of tris HCl powder in 100 microliters of deionized water.
