A nanolithographic technique, electrophoretic printing lithography (EPL), is developed to generate heterogeneous biomolecular nanopatterns. By applying electric potentials on metal nanoelectrodes on a stamp, charged nanoparticles coated with distinct biomolecules are assembled onto the nanoelectrodes by electrophoretic deposition to generate heterogeneous biomolecular nanopatterns, which can then be printed from the stamp to a biocompatible polymer film (see image).
