A Virus was dried onto either copper alloy or stainless steel. Virus stock represents virus exposed to only the ambient temperature and light in a sealed micro-centrifuge tube. Each bar is the geometric mean of two technical replicates and two biological replicates (n = 4). Error bars represent the standard deviation. Asterisk indicates at least one replicate was at or below the detection limit. B Virus suspended in three different matrices was dried onto the copper alloy. Each bar is the geometric mean of two technical replicates and two biological replicates (n = 4). Error bars represent the standard deviation. Asterisks indicate at least one replicate was at or below the detection limit
