Graphene Field Effect Transistor (G-FET) (IMAGE) Boston College Caption The difficulty and expense of determining the precise pathogen causing an infection is a key part of the complexity of antibiotic treatments. 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.
