Faster, cheaper method for detecting pathogens
Researchers at MIT, the Max Planck Institute, and Berlin Univ. have developed a new method for detecting foodborne pathogens. The methodology is based on liquid droplets (called Janus emulsions) that can bind to bacterial proteins. This interaction, which can be detected by either the naked eye or a smartphone, could offer a much faster and cheaper alternative to existing food safety tests. The researchers’ work appeared in a paper “Janu…
