Abstract
A device (100) for detecting an analyte (132) includes a polymer material (112) over a substrate (110); a heat transfer element (114) thermally coupled to the substrate; a temperature modification device (118) thermally coupled to the heat transfer element; a controller (121) to produce a thermal (202) wave emanating from the heat transfer element; a flow cell (122) located and configured to pass a liquid (124) over the polymer material; a temperature sensor (134) to detect a temperature (T2) of the liquid passing over the polymer material; and a processor (123) to calculate a concentration of an analyte (132) in the liquid based at least in part on a phase shift between the thermal wave at the heat transfer element and an attenuated thermal wave (204) in the liquid. Related methods of forming such a device and detecting analytes are also disclosed.
