Micrographs of typical electrospray printed deposits. (a) Stationary substrate with a spray time of 10 s and a separation distance of 7.5 mm and (b) Translating substrate with a velocity of 1 mm/s and separation distance of 7.5 mm. Both images were converted to binary and highly processed for visualization in this figure. The box along the center of the deposits represents the region of interest (ROI). In these regions, particle counts and locations are calculated for analysis. The height of the ROI is exaggerated for clarity. The scale bars are 750 μm.
