(22nd International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2018). Acoustophoresis. Our approach to separate CTCs from white blood cells is using a label-free ultrasound standing wave-based microfluidics platform called Acoustophoresis (Magnusson et al 2017, Antfolk et al 2015, Augustsson et al 2012). This cell separation is based on intrinsic cellular properties such as size, density and compressibility. The aim of this thesis was to compare different ways of dissociating tissue - specifically breast cancer tissue - and sorting out tumour cells and immune cells from the dissociated tissue using acoustophoresis in a microfluidic chip. Microfluidic, Label-Free Enrichment of Prostate Cancer Cells in Blood Based on Acoustophoresis Forskningsoutput : Tidskriftsbidrag › Artikel i vetenskaplig tidskrift Översikt 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 -A SOUND APPROACH TO CHIP BASED CELL HANDLING – T.

This new treatment, which is now being trialled by The Institute of Cancer Research, London, Often called throat cancer, this disease occurs more commonly in men. The prognosis is quite good compared to most other cancers, especially when compared to 3 Jan 2019 A clinical trial aims to find out if early cancer signs can be picked up in breath samples. 31 Oct 2015 The researchers – working at the Institute of Cancer Research (ICR), at the Royal Marsden hospital in Sutton, outside London – have already 18 Dec 2019 [33] have isolated breast cancer cells (MCF7) from peripheral blood with an efficiency of 91.8 ± 1.0% based on an integrated acoustophoresis- 5 Jun 2019 938-43.

Throat cancer refers cancer that develops in your throat (pharynx) or voice box (larynx). Your throat is a muscular tube that begins behind your nose and ends in your neck. Throat cancer most often begins in the flat cells that line the inside of your throat. Microchannel acoustophoresis has been evaluated for isolation of prostate and breast cancer cells from blood. Cancer cells are discriminated primarily based on their higher acoustophoretic mobility as compared to the white blood cells (WBCs).

Resistive pulse sensing (RPS) is a key label-free technology to measure particles and single-cell size distribution. As a growing corpus of evidence supports that cancer cells exhibit distinct mechanical phenotypes from healthy cells, expanding the method from size to mechanical sensing could represent a pertinent and innovative tool for cancer research. Traditional acoustophoresis cell handling typically displays a lower size limit of about 2 micrometers. However, more recent developments have advanced acoustofluidics to enable access also to bacteria and submicron vesicles where the rising interest in extra cellular vesicles and the link to disease biomarkers now is a major focus area. Acoustophoresis does not affect cell viability or proliferation. To determine whether acoustophoresis had any detectable effect on the intrinsic properties of viable cancer cells, we measured cell viability at two temperatures (25.0 ± 0.5°C and 37.0 ± 0.5°C) subsequent to acoustophoretic processing.

Cancer cells are discriminated primarily based on their higher acoustophoretic mobility as compared to the white blood cells (WBCs). cancer cells and study the different properties of cell respiration using human leukocytes and thrombocytes. Our studies indicate that microchannel acoustophoresis can be tuned for effective cell handling without having any effect of cell viability, proliferation, respiration or inflammatory status.
