The present invention provides a composite material including a substrate having an oxide surface, and, a continuous monolayer on the oxide surface, the monolayer including a silicon atom from a trifunctional alkyl/alkenyl/alkynyl silane group that attaches to the oxide surface, an alkyl/alkenyl/alkynyl portion of at least three carbon atoms, a polyalkylene glycol spacer group, and either a reactive site (e.g., a recognition ligand) or a site resistant to non-specific binding (e.g., a methoxy or the like) at the terminus of each modified SAM. The present invention further provides a sensor element, a sensor array and a method of sensing, each employing the composite material. Patterning is also provided together with backfilling to minimize non-specific binding.
本发明提供了一种复合材料,包括具有氧化表面的基底和连续单层,单层包括来自三官能基烷基/烯基/炔基硅烷基团的硅原子,附着在氧化表面上,至少有三个碳原子的烷基/烯基/炔基部分,聚乙二醇间隔基团,以及每个修饰SAM的末端具有反应位点(例如,识别配体)或对非特异性结合具有抗性的位点(例如,甲氧基或类似物)。本发明还提供了一种传感器元件、传感器阵列和感应方法,每种都采用该复合材料。此外还提供了图案设计和回填以最小化非特异性结合。
