Using a graphene field-effect transistor biosensor, we monitored the pH inside a living biofilm
with fast temporal resolution (~ 1 s) over multi-hour time periods. The atomically-thin sensor is
positioned between the biofilm and a supporting silicon oxide surface, providing non-invasive
access to conditions at the base of the biofilm....
