a The standard deviation (σ) for the normalized intensity in the cross-sectional confocal microscopy image versus the distance from T-junction for different micromixers (plain microchannel and microchannels with one side, three sides, four sides patterned) at a flow rate of 10 μL/min. b σ value versus the distance from T-junction for the plain channel and the 3D channels with three sides patterned at different flow rates of 10 and 40 μL/min
