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

Hematopoietic progenitor cell assays revealed a preserved colony forming ability of nontarget cells post sorting. We conclude that the acoustophoresis platform can be utilized to efficiently isolate bead-labeled CD4+ lymphocytes from PBPC samples in a continuous flow format, with preserved functional capacity of both target and nontarget cells.

The technology is currently finding increased applications in bioanalytical and clinical applications of cell handling and manipulation. Acoustophoresis is a microfluidic technology that uses ultrasound for the separation of cells based on their acoustophysical properties.

2013-05-27 Acoustophoresis, the ability to acoustically manipulate particles and cells inside a microfluidic channel, is a critical enabling technology for cell-sorting applications. However, one of the major impediments for routine use of acoustophoresis at clinical laboratory has been the reliance on the inherent physical properties of cells for separation. Cancer cells display acoustic properties enabling acoustophoretic separation from white blood cells (WBCs) with 2–3 log suppression of the WBC background. However, a subset of WBCs has overlapping acoustic properties with cancer cells, which is why label-free acoustophoretic cancer cell isolation needs additional purification prior to analysis.

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.

By moving blood cells in an acoustic field from a standing half-wave, pure plasma was generated at 10 µl/min. The acoustophoresis separation device is a silicon/glass microchannel [7] having a trifurcation inlet and outlet, Fig. 1. A piezoceramic crystal actuates the separation channel at /2 resonance, creating a force on suspended cells directed to-wards the vertical center plane of the channel.
