Fabrication and BSA Adsorption/Desorption Properties of Titania/Silica Composite Films Modified with Silane Coupling Agents

: In this study, we successfully prepared titania/silica composite films modified with silane coupling agents having amino groups and investigated their bovine serum albumin (BSA) adsorption/desorption behavior under light irradiation. XRD patterns and ATR/FT-IR spectra of the films revealed the formation of titania/silica composite films modified with silane coupling agents. In these films, the adsorption and desorption of BSA could be controlled by light irradiation, through the locally photoinduced superhydrophilic titania surface.
