Abstract
A device for detecting an analyte includes a thermocouple having an assay polymer over a surface of the thermocouple. The assay polymer is formulated to bind to the analyte, and a heat transfer property of the assay polymer varies responsive to an amount of the analyte bound thereto. A method of forming a sensor includes providing an assay polymer over a thermocouple. A method for detecting an analyte includes passing a liquid containing an analyte adjacent a thermocouple having an assay polymer over a surface thereof, binding an analyte to the assay polymer, detecting a temperature of the thermocouple, and calculating a concentration of the analyte in the liquid based at least in part on the heat transfer property of the assay polymer.
