Abstract
Prefabricated catalyzing adsorption sites are incorporated into small oscillators. In one embodiment, the sites are formed of precisely positioned gold anchors on surface micromachined oscillators. The micromachined oscillators may be formed of silicon, such as polysilicon, or silicon nitride in various embodiments. The sites allow special control of chemical surface functionality for the detection of analytes of interest. Thiolate molecules may be adsorbed from solution onto the gold anchors, creating a dense thiol monolayer with a tail end group pointing outwards from the surface of the gold anchor. This results in a thiolate self-assembled monolayer (SAM), creating a strong interaction between the functional group and the gold anchor.
