templates and electric fields. Some 11.2±0.5 nm iron oxide nanoparticles were synthesized
and dispersed in toluene. Electrophoretic mobility measurements indicate that most
nanoparticles have a small excess charge. Using a parallel plate geometry, a voltage is
applied to drive particles toward electrodes submersed in the nanoparticle dispersion.
These electrodes are either bare silicon wafers or Si nanopatterned with hydrogen …
