Electrophoretic deposition of calcium phosphate nanoparticles on a nanostructured silicon surface

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.
