Extremely sensitive nanosensor chips are being developed by Stanford University researchers in an attempt to detect the early signs of cancer, called biomarkers, in humans. The researchers say their sensor is around 1,000 times more sensitive than current technology and is accurate regardless of which bodily fluid is being analyzed. It can also detect biomarker proteins over a range of concentrations three times broader than any existing method. It is forecast that earlier detection of cancer biomarkers will lead to improved survival rates among cancer sufferers.
