  1. The measurement of fluids viscosity represents a huge need for many biomedical and material applications. Sample fluids containing DNA, antibodies, proteins, and even cells have become important therapeutical options. The physical properties, including viscosity, of these biologics are critical factors in the optimization of the biomanufacturing processes. Here we demonstrate an acoustic microstreaming platform that induces fluid transport from second-order microstreaming. We validate our platform with water-glycerol mixture to reflect different viscosities and measure the maximum speed of the second-order acoustic microstreaming within seconds. Our demonstrated platform does not require external instruments to pump fluids and consumes small amount of fluid sample (< 10 uL) and is easy to incorporate with automation systems.
