Researchers
have developed a hybrid nanosensor incorporating magnetic resonance and
fluorescence. Lab testing of milk showed the detector
could sense varying concentrations of a pathogenic strain of E. coli known as O157:H7 in less than an
hour. They also used their sensor to analyze E. coli levels in untreated lake water, which serves as a source of
household water in some developing areas. Additionally, the device could be
customized to detect a wide range of pathogens beyond E. coli.
