Patent ID: 7083985

Claim:
A coplanar waveguide biosensor for detecting molecular or cellular events, comprising: a one-port coplanar waveguide transmission line operable to support the propagation of a electromagnetic test signal, comprising: a signal line configured to conduct a time-varying voltage therealong, wherein the signal line comprises a tapered section; and one or more ground elements configured to maintain a time-invariant voltage therealong, the one or more ground elements spaced apart from the signal line and located generally within the same plane as the signal line, wherein a detection region is formed between a portion of the signal line and a portion of at least one of the one or more ground elements; and a sample containment structure intersecting the detection region of the one-port coplanar waveguide transmission line, wherein the sample containment structure comprises a cavity operable to hold 1 ml or less of sample solution within the detection region.
