Abstract:
1. A method of detecting a target analyte in a test sample, the method comprising: providing a substrate for supporting biological analyzer molecules, the substrate including at least one scanning pathway, locating a plurality of scanning targets along the scanning pathway, the plurality of scanning targets alternating periodically between a group of a first set of targets and a group of a second set of targets, the first set of targets including specific biological analyzer molecules adapted to detect the target analyte, and the second set of the targets not including the specific biological analyzer molecules; contacting a test sample to the plurality of scanning targets; scanning the plurality of scanning targets along the at least one scanning pathway at a rate to create a carrier frequency signal and sideband signals, the binding of the target analyte to the specific analyzer molecules of the first set of targets modulating the carrier frequency signal to create the sideband signals; detecting the sideband signals; and determining the presence or absence of the target analyte in the test sample based on the sideband signals.
