(with Leslie Yeo) Surface acoustic wave devices offer unprecedented power densities in microfluidics devices, and my talk will illustrate some of the more fascinating uses of that energy. SAW-induced atomization may be used to form monodisperse microdroplet aerosols and nanoparticle sprays of insulin and other large biomolecules without risk of damage to the molecules. Curiously, the underlying theory predicting droplet sizes from ultrasonic atomization dating from Michael Faraday’s work in 1851 has serious flaws that stand out when using SAW; we discuss a more appropriate physical model and the appearance of capillary wave turbulence. Pumping of fluids in channels and as free sessile droplets is well-known, but the underlying mechanisms leading to pumping are surprisingly complex—pumping with and against the SAW propagation direction in the same device is entirely possible, and we show the reasons why. Further, we show peculiar particle collection phenomena during pumping and the formation of lateral instabilities that give rise to mixing in channels with widths greater than the acoustic wavelength in the pumped fluid. Finally, the energy provided by SAW is known to heat fluids via viscous losses, but this along does not explain the incredible enhancement of organic reactions like trypsin digestion, ubiquitous in biochemistry and normally yielding only 40% completion to products after waiting eight hours, to a convenient 8-minute, 85% complete reaction by exposure to SAW. Potential mechanisms and discussion of other interesting chemical effects will be covered as well.
