But because of a concerted effort by polluters and developers, and muddied rulings from the U.S. Supreme Court, up to 60 percent (at least 15,000 important waters) have lost these vital protections and countless other waters (including more than 50 percent of our streams and 20 million acres of wetlands) are at risk of losing protections. Today, Natural ... |

Fitting pieces for biosensors
Research and industry are increasingly exploiting the potential of aptamers. As well as their application in research, medical diagnosis and treatment, aptamers are also interesting as a basis for biosensors for use in environmental analysis because their characteristics enable them to identify and bind target molecules as surely as a key fits a lock. In a new book, researchers at the Helmholtz Centre for Environmental Research (UFZ) describe the methods used to obtain aptamers. A newly-approved project aims to develop new nanostructured biosensors to measure harmful substances in water. The ... |
