(a) PEG-700 with and without fluorescein dye, and bubbles are smoothly flowing along the microchannel in the absence of an acoustic field, displaying no significant mixing due to bubble generation. (b) When the piezoelectric transducer is turned ON (~100 VPP), 100 % PEG-700 with and without fluorescein dye are mixed in 50 milliseconds. (c) Grayscale intensity plot (normalized to 1) along the dotted lines in (a) and (b) shows homogenous mixing after the acoustic transducer is turned ON.
