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.
在本研究中，我们成功制备了用含氨基的硅烷偶联剂改性的二氧化钛/二氧化硅复合薄膜，并研究了它们在光照下的牛血清白蛋白（BSA）吸附/解吸行为。薄膜的XRD图谱和ATR/FT-IR光谱表明形成了用硅烷偶联剂改性的二氧化钛/二氧化硅复合薄膜。在这些薄膜中，通过局部光诱导的超亲水二氧化钛表面，BSA的吸附和解吸可以通过光照来控制。
