Ultra-sensitive biosensor could detect diseases in their earliest stages

A new ultra-sensitive test developed by scientists from the Imperial College London and Spain’s University of Vigo has the potential to detect the earliest stages of a disease, thereby giving any treatment the best possible chance of succeeding. The researchers claim their new biosensor test is capable of detecting biomarkers (molecules which indicate the presence of a disease) at concentration levels much lower than is possible with existing biosensors. While the new test has already proven capable of detecting a biomarker associated with prostate cancer, the team says their biosensor could be easily reconfigured to detect biomarkers related to other diseases or viruses. http://www.gizmag.com/ultra-sensitive-biosensor/22703/
