Photoswitched protein adsorption on electrostatically self-assembled azobenzene films

Chemphyschem. 2012 Aug 6;13(11):2671-5. doi: 10.1002/cphc.201200231. Epub 2012 May 22.

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.
