Fig. 2From: Survival strategy of Pseudomonas aeruginosa on the nanopillar topography of dragonfly (Pantala flavescens) winga Quantitative viability analyses of P. aeruginosa ATCC 9027 and PAO1 on coverslip and wing using flow cytometer. b Fluorescent microscopic images of P. aeruginosa stained with SYTO9 and propidium iodide. Live cells appear green and, dead cells appear red. c Quantity of DNA in the P. aeruginosa suspension incubated with glass coverslip and dragonfly wings for discrete time intervals. d Number of P. aeruginosa cells attached to coverslip and wings enumerated using hemocytometer after incubation for 30 min through 48 h. *Represents statistical significance p < 0.05 using paired t-testBack to article page
