175–177 FFA uses acoustic forces generated by high-frequency acoustic resonators to separate particles or cells based on their size, density and compressibility. 177,178 As a suspension passes along a flow Lenshof, A., Laurell, T.: Continuous separation of cells and particles in microfluidic systems. Chem. Soc. Rev. 39(3), 1203–1217 (2010) Google Scholar Here, we investigated the performance of microfluidic acoustophoresis for the separation of CD8+ lymphocytes from PBPC, and present a method for affinity-bead-mediated acoustic separation of cells which otherwise cannot be discriminated acoustically. Acoustophoresis is a microfluidic technology that uses ultrasound for the separation of cells based on their acoustophysical properties. In acoustophoresis, the movement of particles in liquids is controlled by a half‐wavelength ultrasound standing wave field generated across a microchannel (Fig.

Acoustophoresis cell separation

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. Label-free neuroblastoma cell separation from hematopoietic progenitor cell products using acoustophoresis - towards cell processing of complex biological samples.

fractionation of red cells, platelets, and leukocytes. 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

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. Binary separation of particle/vesicle/cell mixtures into two subpopulations is outlined based on the different polarities of the acoustic contrast factor.

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. 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.

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%. There was no detectable loss of cell viability or cell proliferation subsequent to the exposure of viable tumor cells to acoustophoresis.

To accomplish this, the magnetic particles are bound to specific cell surface proteins on the target cells via antibodies, enzymes, lectins, or streptavidin. 11. 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.

Free Flow Acoustophoresis (FFA) can be considered as one of the most efficient approaches for high-throughput separation of microparticles or cells from complex suspensions such as blood samples. 31,173,174 A dedicated review series has been written on the subject. 175–177 FFA uses acoustic forces generated by high-frequency acoustic resonators to separate particles or cells based on their size, density and compressibility. 177,178 As a suspension passes along a flow Lenshof, A., Laurell, T.: Continuous separation of cells and particles in microfluidic systems.
