A glass plate with a nanoscale roughness could be a simple way for scientists to capture and study the circulating tumor cells that carry cancer around the body through the bloodstream.
Engineering and medical researchers at the University of Michigan have devised such a set-up, which they say takes advantage of cancer cells' stronger drive to settle and bind compared with normal blood cells.
Circulating tumor cells are believed to contribute to cancer metastasis, the grim process of the disease spreading from its original site to distant tissues. Blood tests that count these cells can help doctors predict how long a patient with widespread cancer will live.
