BAndpass particle sorting in cascade acoustofluidic system for drinking water monitoring

This paper demonstrates the bandpass particle sorting by using a cascade acoustofluidic system, in which the targeting particle size is tunable by adjusting the applied voltage. The relationship between particle motion, particle size and applied voltage is discussed. The sorting of 10-μm and 5-μm particles are experimentally demonstrated with a recovery as high as 90% and 80% elimination rate of undesired particles which give targeting particles more than 4 times enrichment. It shows a high potential for different microbial sorting in drinking water monitoring and detection.
