Therefore, it is important that cancer is spotted and dealt with before transition takes place, or a minimum of at its early stages. To spread out the cancer, messenger cells called Distributing Tumor Cells, or CTCs, break off of the initial growth and flow through the bloodstream to create a secondary growth. A team of researchers led by Assistant Teacher of Mechanical and Biomedical Engineering and Principal Investigator at the NYU Abu Dhabi Mohammad A. Qasaimeh, have actually established a new microfluidic system, called the Herringbone Microfluidic Probe (HB-MFP), that effectively separates both CTCs and clusters of CTCs from blood samples of cancer patients for much easier and more informative analysis.

In a new study titled Herringbone Microfluidic Probe for Multiplexed Affinity-Capture of Prostate Flowing Growth Cells, Qasaimeh and his group present the process of developing the HB-MFP tool, which utilizes various types of biorecognition molecules to identify and isolate cells from blood samples. The HB-MFP works in an open setup without involving the concept of closed-channels, which gets rid of a number of technical obstacles with classical microfluidics. As a result, the HB-MFP is mobile and scans over the capture substrate that is decorated with different biorecognition receptors. For analogy, the HB-MFP works like a pen composing on a board under water and without any contact, where the ink is the client’s blood sample and the board is the biofunctionalized substrate for CTCs record.

In one milliliter of a patient’s blood sample, just a few CTCs exist within billions of healthy red and white blood cells. Using prostate cancer blood samples, the HB-MFP effectively separated CTCs with counts ranging from as low as 6 CTCs/mL (localized cancer clients) to as high as 280 CTCs/mL (metastatic cancer clients). In addition, clusters of CTCs as large as a group of 50 cells were effectively jailed. These brand-new findings are released in the journal Advanced Materials Technologies.

“The analysis of the number, antigen expression levels, and sizes of recorded CTCs potentially holds fantastic promise to act as a diagnostic and prognostic tool for prostate cancer,” commented Ayoub Glia, the very first author and a Ph.D. candidate at Qasaimeh Group.

Physical exams and determining prostate specific antigen (PSA) serum levels are the two standards for early prostate cancer detection. Nevertheless, these procedures have shown to be unreliable and intrusive. Liquid biopsy techniques, a diagnosis tool using blood samples, requires little sample volumes and offers high precision, therefore attaining greater sensitivity at a lower expense.

“The HB-MFP blazes a trail for more effective liquid biopsies and can be adjusted to other kinds of cancers, such as breast cancer and lung cancer, by slight modifications,” stated Qasaimeh. “It is our hope that our work will help make early diagnostic tools more efficient and precise.”
