Researchers at the National Institute of Technology in Nagaland, India have developed a lab-on-a-chip device that utilizes dielectrophoresis (DEP) to separate circulating tumor cells (CTCs) from blood cells. The device, designed using positive and negative DEP techniques, achieved nearly 100% separation purity and efficiency for lung and breast cancer CTCs. The researchers used numerical simulation to investigate different electrode geometries, voltages, and flow velocities. This thorough and methodical design could lead to the development of DEP-based cell separation biochips. [Extracted from the article]
