Acoustophoresis uses an ultrasonic standing wave in a microchannel which differentially affects the movement of cells depending on their acoustophysical properties, such as size, density, and compressibility. Human bone marrow MSCs were generated by standard adherent culture in xenofree medium and separated by microchip acoustophoresis.

Acoustophoresis holds great promise as a cell separation technique in several research and clinical areas. Acoustophoresis is a technique that applies ultrasonic standing wave forces in a microchannel to sort cells depending on their physical properties in relation to the surrounding media. Cell handling and separation for research and clinical applications aims to efficiently separate specific cell populations. We have previously reported the use of a novel ultrasound-based sorting technology, called acoustophoresis, for sorting of platelets (Dykes et al., PloS one 2011) and CD4+ cells from PBPC products (Lenshof et al., Cytometry Part A 2014). Acoustophoresis is a very attractive, gentle label-free and noncontact method of particles and cell manipulation/separation due to its induced motion when subjected to an acoustic field. It is the migration of cells or particles with sound. On exposure to an acoustic wave field, radiation force affects particles.

With its  Acoustophoresis, which means migration with sound, uses ultrasound in combination with microfluidic channels or cavities to move particles or cells in a controlled way. As ultrasound has wavelengths matching microfluidic channel dimensions, a standing wave can be created between the wall of a microfluidic channel. Therefore, CTC isolation systems relying on epithelial cell markers are at risk of losing important subpopulations of cells.

On exposure to an acoustic wave field, radiation force affects particles. There was no detectable loss of cell viability or cell proliferation subsequent to the exposure of viable tumor cells to acoustophoresis. For nonfixed, viable cells, tumor cell recovery ranged from 72.5% to 93.9% with purity ranging from 79.6% to 99.7%.

Circulating tumor cells can also be extracted from blood by means of acoustophoresis, where the differing acousto-physical properties of circulating tumor cells are explored as the basis for separation from other peripheral blood cells. A first effort to capitalize on this aspect was recently reported

PLoS ONE, 6, e23074, (2011) Google Scholar 16. Microchannel acoustophoresis has been evaluated for isolation of prostate and breast cancer cells from blood. Cancer cells are discriminated primarily based on their higher acoustophoretic mobility as compared to the white blood cells (WBCs). 2019-06-19 · Blood cells and neuroblastoma cells differ in size and acoustic properties. The efficiency in separating different cell types with acoustophoresis is depending on differences in their Due to the travel time between acoustophoresis and RPS chips, a delay is observed between sorting and detection events. When the acoustic power is high, both cells and microspheres are observed, whereas at lower power, only the microspheres are detected.
