title: Photoswitched protein adsorption on electrostatically self-assembled azobenzene films.
abstract: Photoresponsive polymeric films fabricated by a facile electrostatic self-assembly technique are utilized to switch protein adsorption by light irradiation. The introduction of SiO(2)  nanoparticles on the substrate results in a large reversible change of both wettability and protein adsorption.
