UCLA Researchers Develop Nano Device That Can ‘Grab’ Free-Floating Cancer Cells in Bloodstream

Acting like Velcro, the tumor cells are grabbed by the nanopillars on the device
The ‘nano-Velcro’ technology was engineered on a 2.5 x 5 centimeter microfluidic chip, and has been successfully demonstrated by the team. Circulating tumor cells (CTCs) are a large component of cancer-related deaths in patients with solid tumors., since the CTCs are able to leave the primary tumor and travel through the blood stream to establish colonies in other body parts. By testing blood samples using the nano-chip, doctors would be able to perform a “liquid biopsy” allowing for early detection, and improving cancer monitoring and patient responses to treatment.
