Title:
PERMITTIVITY BASED DETECTION OF IMMUNOBIOLOGICAL SPECIFIC BINDINGS IN A CAPACITIVE CELL OF COPLANAR WAVEGUIDE OR MICROSTRIP LAYOUT USING A MICROWAVE
Document Type and Number:
WIPO Patent Application WO2006107972
Kind Code:
A3
Abstract:
A device includes a splitter that splits a time varying signal into two substantially equal power signals. A reference capacitor having a fluidic channel between capacitor plates is coupled to one of the equal power signals and a detection capacitor having a fluidic channel between capacitor plates is coupled to the other of the equal power signals. A detector is coupled to outputs of the reference capacitor and detection capacitor. The signals are shifted 180 degrees from each other in the absence of an analyte in the fluidic channel at or prior to the detector. In one embodiment the device is formed of microstrip circuit elements, or planar waveguide elements, and operates at microwave frequencies.
