opments of microchip acoustophoresis in clinical applications as well as in flow cytometry is reported. KEYWORDS: Acoustophoresis, acoustic standing wave, cell separation, cell handling INTRODUCTION The use of acoustic standing wave forces has in recent years become a viable strategy for advanced cell manipulation and separation (acoustophoresis). Radiation forces in the acoustic standing wave field move the cell-bead complex faster to the center compared to non-target cells and can be separated in the center outlet of the channel (c). Non-target cells exit through the side outlets (d). The total length of the acoustophoresis microchip is 35mm. Figure 1. Acoustophoresis has gained increasing attention as a gentle, non-contact, and high-throughput cell and particle separation technique.

The results show that free flow acoustophoresis can be used to perform complex separation tasks, thereby offering an alternative to expensive and time-consuming methods currently in use. Although separation of suspended micrometer-sized or smaller Culture‐expanded mesenchymal stromal cells (MSCs) are promising candidates for clinical cell‐based therapies. MSC products are heterogeneous and we therefore investigated whether acoustophoresis, an ultrasound‐based separation technology, could be used for the label‐free enrichment of functionally different MSC populations. opments of microchip acoustophoresis in clinical applications as well as in flow cytometry is reported.

Acoustophoresis cell separation and sorting technique. Acoustic cell separation and sorting techniques rely on the fact that cells and particles suspended in fluid experience an acoustic radiation force when they are exposed to ultrasound. The acoustophoresis separation device is a silicon/glass microchannel [7] having a trifurcation inlet and outlet, Fig. 1.

Reducing WBC background in cancer cell separation products by negative acoustic contrast particle immuno-acoustophoresis Kevin Cushing a,1, Eva Undvall a,1, Yvonne Ceder b, Hans Lilja c, d, e On the basis of these findings, we anticipated that the separation of cancer cells from blood would be greatly improved with regard to WBCs, compared to previously reported acoustophoresis-based methods of cell separation. 21 A dramatic improvement was indeed seen, yielding tumor cell recoveries of 87 and 83% of fixed tumor cells (DU145 and PC3, respectively) and a corresponding WBC For cells ﬁxed with paraformaldehyde, cancer cell recovery ranged from 93.6% to 97.9% with purity ranging from 97.4% to 98.4%.
