An acoustic wave biosensor comprising a surface of a mixed self-assembling monolayer for receiving a probe-biomolecule is described herein. The biosensor surface may comprise a piezoelectric quartz crystal,—for detection purposes with the electromagnetic piezoelectric acoustic sensor (EMPAS)—upon which a mixed self-assembling monolayer is formed, which includes at least one linker, such as 2,2,2-trifluoroethyl-13-trichlorosilyl-tridecanoate (TTTA); its oligoethylene glycol (OEG) analog OEGylated TTTA (OEG-TTTA); S-(2-(2-(2-(3-trichlorosilyl-propyloxy)-ethoxy)-ethoxy)-ethyl)-benzenethiosulfonate (OEG-TU BTS). Linker/diluent systems for attaching a functionalizing entity to the surface of a biosensor are described, as well as methods for preparing a biosensor surface with an oligoethylene glycol linker.
这里描述了一种声波生物传感器,包括用于接收探针生物分子的混合自组装单分子层的表面。生物传感器表面可能包括压电石英晶体,用于检测目的与电磁压电声传感器(EMPAS)一起使用,其上形成了混合自组装单分子层,其中包括至少一种连接剂,如2,2,2-三氟乙基-13-三氯硅基-十三酸酯(TTTA);其寡乙二醇(OEG)类似物OEG化的TTTA(OEG-TTTA);S-(2-(2-(2-(3-三氯硅基-丙氧基)-乙氧基)-乙氧基)-乙基)-苯基硫酸酯(OEG-TU BTS)。描述了用于将功能化实体连接到生物传感器表面的连接剂/稀释剂系统,以及使用寡乙二醇连接剂制备生物传感器表面的方法。
