Researchers use Nanotech to Detect Early-Stage Cancer

Stanford University researchers used nanotechnology and magnetics to create a biosensor that they said should be able to detect cancer in its early stages, making a cure more likely. The sensor, which sits on a microchip, is 1,000 times more sensitive than cancer detectors used clinically today, according to scientists at Stanford. The researchers announced this week that the sensors have been effective in finding early-stage tumours in mice, giving them hope that it can be equally successful in detecting elusive cancers in humans
