Catching Tumor Cells with Magnetized Wires

Jul-17-18 A magnetized wire able to detect cancer cells in blood could offer an earlier detection than current blood tests for the disease.

Developed by a team from Stanford University, the technology relies on specially engineered, magnetic nanoparticles that bond to the free-floating tumor cells. As the tumor cells move past a tiny, magnetized wire inserted in the bloodstream, they attach to the wire and can be removed for analysis.

In tests on pigs, the magnetic wire was able to collect ten to eighty times more cancerous cells than a standard blood sample test.
