Microfluidic Device Sorts Cells by Size to Detect Cancer

Feb-28-19 A microfluidic device that sorts cells by size offers an inexpensive way to detect cancer cells in blood samples.

Developed by teams from the University of Illinois and Queensland University of Technology, the device differs from other blood tests for cancer in that it does not rely on biomarkers. Rather, the microfluidic tool will separate the circulating tumor cells by size—a simpler and extraordinarily effective method. In tests, the device was able to capture 93 percent of the CTCs in a 5 ml blood sample with 50 CTCs, and 83 percent in a sample with only 10 CTCs.
