AVOIDANCE OF NON-SPECIFIC BINDING ON AN ACOUSTIC WAVE BIOSENSOR USING LINKER AND DILUENT MOLECULES FOR DEVICE SURFACE MODIFICATION |
摘要 |
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-TUBTS). 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.
