A new biosensor based on an antibody system has been designed and tested by researchers at the Virginia Institute of Marine Science. The sensor can detect marine pollutants, such as oil, much more quickly and at lower cost than current technologies, the developers say. They add that the device is small and sturdy enough to be used from a boat. "Our biosensor combines the power of the immune system with the sensitivity of cutting-edge electronics," explains VIMS' Mike Unger. "It holds great promise for real-time detection and monitoring of oil spills and other releases of contaminants into the marine environment."
