Scientists develop 'more accurate, fast Covid test' method to detect single virus particles
coronavirus tests.The study, which has been published in the journal ACS Sensors, demonstrated a new system for identifying single virus particles using an algorithm trained to detect changes in the current passing across silicon nanopores.According to the scientists, including those from Osaka University in Japan, the work may lead to fast and accurate screening tests for diseases like COVID-19 and influenza.In the new method, the scientists said a layer of the compound silicon nitride just 50 nanometres (nm) thick has tiny nanopores added.The layer is suspended on a silicon wafer, they said, adding that when a voltage difference is applied to the solution on either side of the wafer, ions travel through the nanopores in a process called
