Microscale acoustofluidics defines the use of ultrasonic waves onto a fluid inside a microchannel. The acoustic waves are imposed on the fluid through excitation of the microchannel walls with an actuator.

Microfluidics is often aimed at producing Lab-on-a-Chip based systems, particularly useful for testing in remote locations where standard laboratory techniques are not available. Acoustophoresis holds advantages over many other particle manipulation methods as it only alters the fluid pressure to displace the non-homogeneous elements within the fluid.

AU - Nilsson, Johan Keywords acoustophoresis, cell separation, clinical, microfluidics, lab-on-a-chip Introduction Acoustic forces have been used for decades to manipulate particulate matter, although the major efforts have targeted larger chamber and batch-processing systems. 1 These devices mainly used the acoustic force to agglomerate particles into larger clusters, which eventually sedimented and clarified Microfluidic, Label-Free Enrichment of Prostate Cancer Cells in Blood Based on Acoustophoresis | Analytical Chemistry Circulating tumor cells (CTC) are shed in peripheral blood at advanced metastatic stages of solid cancers. Surface-marker-based detection of CTC predicts recurrence and survival in colorectal, breast, and prostate cancer. BAW acoustophoresis has formerly focused on cell and particle handling, whereas here we determine the various abilities of this method for the field of droplet microfluidics.

Acoustophoresis Acoustophoretic particle focusing is a modern and very attractive method of removing a variety of objects from solutions in a microfluidic channel. The process is applicable to healthcare applications (malignant cell removal), academic research (nanoparticle separation), industrial applications (reclaiming of rare earths) and environmental applications (sequestration of suspended solids).
