Abstract

A method for characterizing bacteria includes passing a liquid containing an analyte comprising a first bacteria and a second bacteria over and in contact with a polymer material on a substrate. The polymer material is formulated to bind to the first bacteria, and the first bacteria binds to the polymer material with a higher affinity than the second bacteria. A heat transfer property of the polymer material varies based on an amount of the analyte bound thereto. The method further includes binding a portion of the first bacteria and the second bacteria of the analyte to the polymer material, removing at least a portion of the second bacteria from the polymer material, detecting a temperature of the substrate, and calculating a concentration of the first bacteria in the liquid based at least in part on the temperature of the substrate.
