Graphene underpins a new platform to selectively ID deadly strains of bacteria

A team led by Boston College researchers has developed a prototype sensor that uses an atom-deep sheet of graphene and peptides to rapidly reveal which bacterial species is in a sample and whether it is antibiotic resistant. The graphene field effect transistor (G-FET) achieved single-cell resolution and a 5-minute detection time, which could lead to more accurate targeting of infections with appropriate antibiotics.
