Russian & Indian Scientists Develop Tiny Device to Hunt Down Cancer Cells in Blood
Cancer cell
The coin-sized device can detect circulating cancer cells (CTCs) that break away from a tumor and travel through the bloodstream, potentially causing metastases.The new microfluidic chip acts like a microscopic “trap”:blood passes through a maze-like channel inside the chip, whose walls are coated with molecules designed to recognize cancer cellscancer cells stick to the walls, while healthy blood cells continue flowing throughdevice can capture CTCs from just a few millilitres of blood in about 20 minutes, while keeping more than 95% of the captured cells alive and undamagedtests on breast cancer cells showed the chip could detect 80–91% of CTCs without false-positive resultsa single device can be 3D-printed in around 45 minutes, with its molecular “traps” tailored to different types of cancer
The technology could eventually allow doctors to track cancer progression through a routine blood test.
