Microbial biosensor designed to evaluate water toxicity

Researchers of the Environmental Microbiology Group of the UAB Department of Genetics and Microbiology have developed a paper-based biosensor covered with bacteria to detect water toxicity. This is an innovative, simple and inexpensive biological tool that can detect several contaminants and can be easy to use in economically restricted areas, such as developing countries. The paper was recently published in Analytica Chimica Acta.
