Abstract : Photoresponsive monolayers were prepared by the chemisorption of azobenzene-containing molecules to silicate substrates. A reversible change in the water contact angle was observed upon UV irradiation. Neutron reflectometry was used to probe protein adsorption to monolayers. The adsorption of human serum albumin was observed for amine- and methyl-terminated monolayers. Molecular dynamic simulations indicated directions for the next generation of synthetic efforts; the ideal placement for the azobenzene group is near the tail or head of the surface-reactive molecule. jg p1
