Schematic illustration and lengths of a) the herringbone mixer (YHM) and b) obstacle mixer (YOM). c) Distribution profiles of fluorescein concentration along the channel width measured at the Y-channel junction of the mixer chip (used as the peak fluorescence intensity for normalization), after different numbers of pattern repetitions (cycle) for the herringbone mixer (YHM), and after obstacle mixer (YOM). d) Distribution profiles of fluorescein concentration along the channel width for contrasting the influence of mixers (both YHM 3 Cycles and YOM) with the channels of equivalent length (6.9 mm and 38.3 mm respectively) without any mixer patterns
