In (c) and (d), results of RT-PCR tests for supernatants after 10 min exposure of virus suspension to Cu, AlN, and Si3N4 powders for viral N gene "set 1" and "set 2" primers are shown, respectively. The present work is the first to show that compounds capable of endogenous nitrogen-release, such as Si3N4 and AlN, can inactivate the SARS-CoV-2 virus at least as effectively as Cu. These results suggest that multiple antiviral mechanisms may be operative, such as RNA fragmentation, and in the case of Cu, direct metal ion toxicity; but while Cu and AlN supernatants demonstrated strong and partial cellular lysis, respectively, Si3N4 provoked no metabolic alterations. ./cache/cord-349684-2tioh80m.txt ./txt/cord-349684-2tioh80m.txt
