Nanoparticles detect food poisoning bug

imageHOT Nanoscale Communication

Scientists in China have developed a sensitive method for detecting the bacteria Staphylococcus aureus which is a major cause of food poisoning as well as community- and hospital-acquired infections.

The researchers functionalized gold nanoparticles with phenylboronic acid which could react with the cis-diol groups found on the bacteria’s surface, causing a detectable colour change.

Using this method they could detect the bacteria down to a concentration of 50 cells per mL.
