Paging Dr. McCoy: a technique that uses a magnetic field to selectively separate tiny magnetic particles, developed at Purdue and Duke universities, could be used to diagnose the presence of many diseases in a single sample within minutes, with a sensitivity up to a million times higher than current methods.
