Abstract:
A bio-assay device configured to detect a molecular binding event formed between a ligand and an antiligand, the bio-assay device comprising:(i) a signal path operable to support the propagation of a test signal at one or more frequencies from 10 MHz to 1000 GHz, said signal path comprising: an electrically conductive transmission line; a ground element; and a dielectric layer interposed between said electrically conductive transmission line and said ground element; and (ii) a molecular binding layer electromagnetically coupled to said signal path, said molecular binding layer comprising said antiligand operable to bind said ligand, wherein said molecular binding layer is located between at least a portion of said electrically conductive transmission line and at least a portion of said ground element.
