Stanford University Scientists have successfully used a magnetic wire to capture tumor cells as an early cancer detection tactic. The wire is threaded into a patient's vein and attracts special nanoparticles that have been bioengineered to adhere to tumor cells traveling through the blood stream. The technique captures 10-80 times more tumor cells than current detection methods. Learn more about the magnetized tumor capturing wire at Stanford University.

If approved for use in humans, the magnetic wire (depicted in gray) would be inserted into a vein in the arm (in light pink) and attract floating cancer cells labeled with magnetic nanoparticles (light green and gray) that have come from the tumor (neon green).
