DNA Nanoball Method Detects SARS-CoV-2 and Other Pathogens with Simple Electronic Device

With just a room-temperature “pot,” a sprinkling of molecules, and a simple electrical device, pathogen DNA detection can now be achieved in under an hour anywhere. These “DNA nanoballs” are the size of certain bacteria and are detectable by a microscope and electrical impedance. Published in Science Advances, this research sets the foundation for developing electrically-based devices for detecting specific targets at the point-of-care setting.
