Two-dimensional nanodiamond monolayers deposited by combined ultracentrifugation and electrophoresis techniques

Dense detonation nanodiamonds deposit has been obtained through a coupled process: Electrophoretic deposition was applied to an ultracentrifugated detonation nanodiamonds suspension. The resulting coating exhibits nearly complete 5 nm thick monolayer coverage of the substrate. The described process is a soft and easily tunable approach, particularly suitable for the development of sensors or the growth of high performance nanodiamond films. The proximity of the adsorbed nanoparticles on the substrate was demonstrated by scanning probe techniques, such as atomic force microscopy and scanning tunneling microscopy.
