Schematic layout of the experimental study

(A) The schematic representation to capture the global dynamics of droplet impact involving fluorescence microscopy, high-speed microscopic interferometry, atomic force microscopy, and backlight imaging of bacterial droplet impact.

(B) Experimental layout depicting the assessment of in vitro viability of bacteria, infection of macrophages by the bacteria retrieved from desiccated dried droplets, and quantification of the expression of virulent genes of bacteria during infection.
