Electric-field-directed assembly of biomolecular-derivatized nanoparticles into higher-order structures.

Abstract

Multilayered structures composed of biomolecule-derivatized nanoparticles can be fabricated by electric-field-directed self-assembly. A microelectrode-array device facilitates the rapid parallel electrophoretic transport and binding of biotin and streptavidin fluorescent nanoparticles to specific sites on the microarray. Control of the current, voltage, and… (More)
