A single inlet two-stage acoustophoresis chip enabling tumor

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.

Chem. Soc. Rev. 39(3), 1203–1217 (2010) Google Scholar 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. General aspects on working with live cells in acoustophoresis systems are discussed as well as available means to quantify the outcome of cell and particle separation experiments performed by Acoustophoresis offers non-contact and label-free cell separation based on size and intrinsic cell properties 14 without being detrimental to cells or altering their phenotype.

Acoustophoretic separations of particles (or cells) in complex, heterogeneous liquid mixtures (e.g., blood) is an efficient method for sorting particle populations into purified fractions. The use of acoustic forces to manipulate particles or cells at the microfluidic scale ( i.e. acoustophoresis), enables non-contact, label-free separation based on intrinsic cell properties such as size, density and compressibility. Acoustophoresis holds great promise as a cell separation technique in several research and clinical areas.

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).

In he clini- Acoustophoresis uses an ultrasonic standing wave field in a microchannel that differentially affects the movement of cells depending on their acoustophysical properties, such as size, density, and compressibility.

However, it has been suggested that the force acting upon cells undergoing acoustophoresis may impact cell viability, proliferation or cell function via subtle phenotypic changes. Acoustophoresis utilizes the phenomenon that cells can be manipulated in an ultrasonic standing wave field in microfluidic devices. In the acoustic wave field cells experience an induced movement based on their acoustophysical properties, either to the channel center (pressure node) or towards the channel walls (pressure anti-node).

We report a new method on how to determine the density and compressibility of individual on acoustophoresis, which utilizes ultrasound radiation forces to provide gentle and eﬃcient discrimination and separation of tumor cells from nucleated WBCs in a microﬂuidic chip. In microchannel acoustophoresis, cells are subjected to a force generated by ultrasonic resonances in the acoustically soft ﬂuid Acoustic waves are able to create pressure nodes along the microchannels. These pressure nodes can cause cells to move to specific regions of the channel. Continuous exposure of the cells to these acoustic waves leads to cell sorting based on their characteristics.
