SARS-CoV-2 was incubated for 1 and 4 h onto CPG, CPG_Cu, and a control confocal glass. After the incubation time, the inoculum was titrated on VERO E6 (pre-treatment); then the glasses were washed with trypsin (post-treatment) and titrated to assess the percentage of viable SARS-CoV-2 retained on bioglasses.
