Second part of the thesis focuses on acoustophoresis. In (paper 5), a multifunctional acoustic microdevice was developed for isolation of cancer cells from red blood cells with a separation efficiency of 92.4% and trapping efficiency of 93%. In (paper 6), microbubbles activated acoustic cell sorter was developed for affinity based cell separation. At a flow rate of 100 μL/min, breast cancer cells (MCF7) spiked into red blood cell-lysed human blood were separated with an efficiency of 91.8 ± 1.0% with a contamination of 0.6 ± 0.1% from white blood cells with a 23.8 ± 1.3-fold concentration of cancer cells. Resistive pulse sensing (RPS) is a key label-free technology to measure particles and single-cell size distribution.

Cancer cells are discriminated primarily based on their higher acoustophoretic mobility as compared to the white blood cells (WBCs). Influence of Acoustophoresis on Viability or Secretory Function of Prostate Cancer Cells. Acoustophoresis-based microfluidic devices are currently being explored as a mean to enrich and discriminate viable from non-viable tumor cells in peripheral blood . Therefore, we initiated a detailed characterization of the viability and secretory function of tumor cells subsequent to subjecting them to acoustophoretic processing.

Materials and Methods Ethics Statement 2013-05-27 · Here, we demonstrate that acoustophoresis affects neither the responsiveness nor the endogenous PSA secretion or PSA secretion induced by R1881 (a synthetic androgen), in prostate cancer cells. Acoustophoresis may therefore be a suitable technique for live CTC isolation from blood. Microchannel acoustophoresis has been evaluated for isolation of prostate and breast cancer cells from blood.

M any types of cancer are diagnosed at the early stages of the disease, enabling treatment with curative intent. However, many patients succumb due to … Prostate cancer cell viability is not affected by acoustophoresis. Cell viability was determined after acoustophoresis (0, 10 and 20 V pp), for four prostate cancer cell lines: DU 145 (a), PC3 (b), LNCaP (c) and VCaP (d). Left panels show the percentage of cell death directly after acoustophoresis measured by trypan blue exclusion. Measuring cancer cell compressibility by acoustophoresis separation experiments. I 22nd International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2018.

The throat includes the esophagus, windpipe (trachea), voice box (larynx), tonsils and epiglottis. 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). cancer cells and study the different properties of cell respiration using human leukocytes and thrombocytes.

Anna Lantz, lnst för Medicinsk Epidemiologi och Biostatistik, Karolinska Institutet, får 388 784 kronor. Projekt: Evaluation and optimization of active surveillance for men living with clinically insignificant prostate cancer. Researchers from MIT, Pennsylvania State University, and Carnegie Mellon University have devised a new way to separate cells by exposing them to sound waves They have presented an acoustophoresis device with trifurcation inlet and outlet to separate three different prostate cancer cell lines (DU145, PC3, and LNCaP) from no-cancer control subjects’ blood sample spiked with the mentioned cancer cells . Second part of the thesis focuses on acoustophoresis.

Request PDF | Acoustophoresis in Tumor Cell Enrichment | This chapter outlines the opportunities and current developments of label-free separation of circulating tumor cell (CTC) from blood cells Label-free concentration of viable neurons, hESCs and cancer cells by means of acoustophoresis† Marina C. Zalis , a Juan F. Reyes , b Per Augustsson , c Staffan Holmqvist , d Laurent Roybon , d Thomas Laurell c and Tomas Deierborg * a 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. Acoustophoresis is a non-contact and label-free mode of manipulating particles and cell populations and allows for implementation of several separation modes . The technology is currently finding increased applications in bioanalytical and clinical applications of cell handling and manipulation. Prostate cancer cell viability is not affected by acoustophoresis. Cell viability was determined after acoustophoresis (0, 10 and 20 V pp), for four prostate cancer cell lines: DU 145 (a), PC3 (b), LNCaP (c) and VCaP (d).
