Fig. 10: (A) Top-down views of the flat and structured surfaces covered with the dyed fluorescent lubricant. (B) Mean red intensity of the flat (diamonds) and structured (squares) surfaces at varying flow rates. Although there is some variation, the lubricant remains clearly present on both surface types. (C) Confocal cross-sections of the channels with the flat and structured surfaces indicated at 100uL/min (upper image) and 1600uL/min (lower image). There is no significant change in the lubricant in either the flat or structured surface between the two flow rates.
