A diazoketo-functionalized alkoxysilane compound was synthesized, and its self-assembled monolayer (SAM) formation was studied on glass and silicon substrates. Infrared spectroscopy was employed to follow the photoreaction in this system, which proved that carboxylic groups were generated from diazoketo groups in the surface of the substrate. Photopatterning of biotin/streptavidin on the diazoketo-functionalized SAM shows the potential of this novel platform for biomolecular patterning.
合成了一种重氮酮官能化的烷氧基硅烷化合物,并研究了其在玻璃和硅基底上自组装单分子层(SAM)的形成。采用红外光谱跟踪该体系中的光反应,结果表明在基底表面重氮酮基团产生了羧基。在重氮酮官能化的SAM上进行生物素/链霉亲和素的光图案化,显示了这个新型平台在生物分子图案化方面的潜力。
