Inactivation of the virus on copper alloy was tested under various conditions. Virus was diluted into either fresh (red) or conditioned media (blue). Log difference represents the change from starting virus concentration to virus concentration at the specified time. Asterisks indicate data with at least one replicate at or below the detection limit. A Virus was exposed to the surface for 24 h with cell debris in the spike concentrations (x-axis). Each condition is the average of biological replicates (n = 2) with error bars representing the range of the data. B A time course analysis of virus inactivation in fresh or conditioned media only. Trend lines (dashed) with standard deviation (grey area) were calculated only using data above the detection limit. Virus Batch A (circles) is the geometric mean of two technical replicates and two biological replicates (n = 4). Virus Batch B (triangles) is the geometric mean of two technical replicates only (n = 2). C ICPOES of leachates from B up to 16 h. Only the alloy’s major constituents are presented. Each sample is the average of two technical replicates and two biological replicates (n = 4). Error bars represent the standard deviation. Lines are not the result of any regression but help to visualize trends in the data
