Researchers at Purdue University have developed a wireless biosensor that contains DNA primers for nCOVID-19 in order to rapidly and non-invasively test for the virus in patient saliva. Current technology for nCOVID-19 testing is often invasive, is not efficient, or involves testing for antibody activity rather than viral strands. The platform created by Purdue researchers features an inkjet-printed gold electrode that allows for communication with a software application so that electronic readout can be conducted on-site. The electrochemical device has been evaluated in-lab at Purdue University with a library of nCOVID-19 DNA primers to achieve distinction between nCOVID-19, the flu, and other viruses for enhanced detection.
