Experimental data This folder contains the experimental data to the figures shown in the main manuscript and Supporting Information. Figure 1: inactivation data after 0 and 60 min for 1-μl droplet experiments at various RH in PBS, SLF and nasal mucus (infectivity titer and genomic copy enumeration). Figure 3: inactivation data after 0 and 60 min for 1-μl droplet experiments at 60% RH in SLF derivatives (infectivity titer and genomic copy enumeration). Figure 4: inactivation data after 0 and 60 min for 1-μl droplet experiments at 60% RH in various albumin:NaCl mass ratios (infectivity titer and genomic copy enumeration). Figure 5: inactivation data after 0 and 60 min for 1-μl droplet experiments at 60% RH with various proteins (infectivity titer and genomic copy enumeration). Figure S1: Control in bulk for data from Figure 1 (infectivity titer). Figure S2: Recovery fraction for data from Figure 1 (GC/GC0). Abbrevations used: GC = Genomic Copies LoQ = Limit of Quantification PFU = Plaque Forming Unit ul = microliter
