Nanostructured silicon surfaces were electrophoretically coated with calcium phosphate nanoparticles. Positively charged calcium phosphate nanoparticles were synthesized by precipitation and then functionalized with poly(ethyleneimine). This permits the electrophoretic deposition on a conductive surface from a dispersion in 2-propanol. The following parameters affected the deposition of the nanoparticles: The deposition potential, the deposition time, and the deposition temperature.
