Magnetic wire used to capture tumor cells in blood for early detection: study

WASHINGTON, July 16 (Xinhua) -- American researchers have developed a magnetic device that could capture scarce tumor cells in bloodstream, which is a potentially swift and effective tactic for early cancer detection.

A study published Monday in the journal Nature Biomedical Engineering revealed that a wire, after being threaded into a vein, could attract special magnetic nanoparticles engineered to catch hold of tumor cells roaming the bloodstream.
