Purdue University researchers have ideated a thermoelectric sensor which selectively identifies exothermic viral pathogen reactions utilizing the Seebeck effect. The sensor offers fast and precise readouts through detecting temperature changes through a voltage readout after interactions of pathogen antigen/antibody. Silicon material is used as the sensor's base material facilitating scale up through standard device fabrication processes. Modification of this technology to pathogen RNA/complementary DNA hybridization amplify the voltage change in patients with low viral load. This sensor can be used for a wide range of diseases with high epidemic potential increasing the utility.
