A novel UV‐initiated surface modification method for the direct functionalization of surface hydroxy groups with thiol‐containing molecules (termed “thiol–ol” modification) is described. This method is based on the oxidative conjugation of thiols to hydroxy groups. We demonstrate that different thiol‐containing molecules, such as fluorophores, thiol‐terminated poly(ethylene glycol) (PEG‐SH), and a
描述了一种新型的紫外线引发的表面改性方法,该方法可通过含巯基的分子直接官能化表面羟基(称为“巯基-醇”改性)。该方法基于硫醇与羟基的氧化缀合。我们表明,不同的含巯基的分子,例如荧光团,硫醇封端的聚(乙二醇)(PEG-SH),和含有半胱氨酸的肽,可以附着到多孔聚(2-羟乙基甲基丙烯酸酯的表面共‐二甲基丙烯酸乙烯酯)。还使用硫醇-醇方法证明了其他带有羟基的表面的直接功能化,微图案的制造以及双图案化。
