Thin films of diamond nanoparticles (DNPs) were prepared by adsorption method on aluminum surface modified with coupling reagents with amino group (AEAPS), vinyl group (VTMS) and carboxyl group (11-phos). QCM measurements revealed that AEAPS-treated surface adsorbs stable DNPs layer that does not desorb by rinsing in water, whereas VTMS did not adsorb DNP and 11-phos adsorbs only a small amount of DNPs. Cross-sectional TEM observation also confirmed stable adsorption of DNPs on the AEAPS surface.
