Abstract: An assembly of metallic MEMS structures directly fabricated on planarized CMOS substrates, containing the application-specific integrated circuit (ASIC), by direct deposition and subsequent microfabrication steps on the ASIC interconnect layers, with integrated capping for packaging, is provided. The MEMS structures comprise at least one MEMS device element, with or without moveable parts anchored on the CMOS ASIC wafer with electrical contact provided via the metallic interconnects of the ASIC. The MEMS structures can also be made of metallic alloys, conductive oxides and amorphous semiconductors. The integrated capping, which provides a sealed cavity, is accomplished through bonding pads defined in the post-processing of the CMOS substrate.

Abstract: Highly selective coated-electrode nanogap transducers for the detection of redox molecules are described. In an example, an analyte detection system includes one or more transducer electrodes having a surface for analyte detection. The surface includes a coating to inhibit direct contact of analyte with the surface of the one or more transducer electrodes.

Abstract: Various embodiments provide devices, methods, and systems for high throughput biomolecule detection using transducer arrays. In one embodiment, a transducer array made up of transducer elements may be used to detect byproducts from chemical reactions that involve redox genic tags. Each transducer element may include at least a reaction chamber and a fingerprinting region, configured to flow a fluid from the reaction chamber through the fingerprinting region. The reaction chamber can include a molecule attachment region and the fingerprinting region can include at least one set of electrodes separated by a nanogap for conducting redox cycling reactions. In embodiments, by flowing the chamber content obtained from a reaction of a latent redox tagged probe molecule, a catalyst, and a target molecule in the reaction chamber through the fingerprinting region, the redox cycling reactions can be detected to identify redox-tagged biomolecules.
