(a) The schematic description of the air flow detachment experimental setup. (b) The average fluorescence intensity represents the number of pseudo-virus binding on the surfaces. The numbers of pseudo-virus particle remaining on the surface after applying air flow for 10 min, 30 min and 1 h were compared to that before applying the air flow at time zero (100%). (n = 5) (c) The comparison of the percentage of detached pseudo-virus particles, represented by the average fluorescence intensity, from the sample surfaces after applying air flow for 1 h. P values from one-way ANOVA Tukey’s test are shown. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
