Azobenzene polymer film was fabricated by spin coating technology on the surface of single crystal silicon. The structure and properties of the film were characterized by FTIR, UV-vis absorption spectroscopy and contact angle tests. The results indicated that the film had excellent photochromism property and the trans-cis isomerization process was in accord with one order reaction of kinetics. Bovine serum albumin could be adsorbed on the film surface reversibly before and after UV light irradiation, so azobenzene polymer film could be used as the sensing membrane of protein chips.
