Title:
ANALYTE DETECTION METHODS AND APPARATUS USING DIELECTROPHORESIS AND ELECTROOSMOSIS
Document Type and Number:
WIPO Patent Application WO/2017/181030
Kind Code:
A3
Abstract:
Methods and apparatus for detection and/or identification of analytes including bacteria using dielectrophoresis and electroosmotic traps. Switching between different frequencies of an applied electric field results in movement of the analyte between dielectrophoresis and electroosmotic trapping states. The use of edge-based sensing techniques enables the use of electrodes with a larger form factor than nanowire sensors. Signal modulation based on analyte contact with the electrode edge is also described.
