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.

This invention provides chimeric molecules that are catalytic antagonists of a target molecule. The catalytic antagonists of this invention preferably comprise a targeting moiety attached to an enzyme that degrades the molecule specifically bound by the targeting moiety. The catalytic antagonists of this invention thus bind to a target recognized by the targeting moiety (e.g., a receptor) the enzyme component of the chimera then degrades all or part of the target. This typically results in a reduction or loss of activity of the target and release of the chimeric molecule. The chimeric molecule is then free to attack and degrade another target molecule.
