Researchers from Bochum, Göttingen, Duisburg and Cologne have developed a new method for detecting bacteria and infections. They use fluorescent nanosensors to track down pathogens faster and more easily than with established methods. A team headed by Professor Sebastian Kruß, formerly at University of Göttingen, now at Ruhr-Universität Bochum (RUB), describes the results in the journal Nature Communications, published online on 25 November 2020.
