Abstract:
A method for detecting a molecular event in a test sample, the method comprising:providing a test structure having a measureable signal response when a test signal is input and an output signal is recovered, wherein the measureable signal response is a resonant response; obtaining a first resonant response of the test structure when the test structure is electromagnetically coupled to a reference sample; obtaining a second resonant response of the test structure when the test structure is electromagnetically coupled to the test sample; deriving one or more electrical parameters from the first resonant response; deriving one or more electrical parameters from the second resonant response; detecting similarity or difference between the electrical parameters derived from the first and second resonant responses as an indication of the molecular event in the test sample; determining the difference between the electrical parameters derived from the first and second resonant response; and indicating that, if the reference sample contains the molecular event and if the difference between the one or more electrical parameters derived from the first and second resonant responses does not exceed a predefined value, the test sample includes the molecular event.
