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. 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. Proliferation of cells was not affected by acoustic separation. These results provide first evidence that NBCs can be acoustically separated from blood and stem cell preparations with high recovery and purity, thus indicating that acoustophoresis is a promising technology for the development of future label-free, non-contact cell processing of complex cell products. 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.

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). Acoustophoresis is a gentle, non-contact, continuous, and label-free separation method for cells and particles. The ability to separate cells with acoustophoresis depends primarily on differences A novel method, free flow acoustophoresis (FFA), capable of continuous separation of mixed particle suspensions into multiple outlet fractions is presented. Acoustic forces are utilized to separate particles based on their size and density.

The method is shown to be suitable for both biological and nonbiological suspended particles. In this thesis, a microfluidic technique called acoustophoresis is evaluated for plasma generation as well as for separation of white blood cells from whole blood. 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.

The method is shown to be suitable for both biological and nonbiological suspended particles. Using this microchannel configuration, several publications have shown cancer cell lines (breast and prostate) being efficiently separated from WBCs from RBC-lysed blood using acoustophoresis with BASWs [3, 20].This label-free separation occurs because larger-sized cancer cells focus faster to the center pressure node than WBCs in the separation channel; thus, if flow rates are optimized the Acoustophoresis enables the label-free separation of functionally different subsets of cultured bone marrow stromal cells Franziska Olm , Hooi Ching Lim , Katharina Schallmoser , Dirk Strunk , Thomas Laurell & Stefan Scheding , 2020 Jun 15 , In : Cytometry. 2018-09-01 2017-12-07 Immunomagnetic cell separation is a technique whereby magnetic particles are used to isolate target cells from heterogeneous mixtures. To accomplish this, the magnetic particles are bound to specific cell surface proteins on the target cells via antibodies, enzymes, lectins, or streptavidin. 11.

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. 2017-12-07 Article I: Label-free neuroblastoma cell separation from hematopoietic progenitor cell products using acoustophoresis - towards cell processing of complex biological samples Article II: Label-free separation of neuroblastoma patient-derived xenograft (PDX) cells from hematopoietic progenitor cell products by acoustophoresis Article III: Acoustophoresis enables label-free separation of functionally different Petersson, F., et al.: Free flow acoustophoresis: Microfluidic-based mode of particle and cell separation.
