  • Graphene Biotransistor Interfaced with a Nitrifying Biofilm

    Creator:
    Brown, Morgan A., Barker, Leila, Semprini, Lewis, and Minot, Ethan D.
    Abstract:
    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....

  • Graphene Biotransistors, an Exploration of Neurosensing and Biofilm-sensing Applications

    Creator:
    Brown, Morgan A.
    Abstract:
    Atomically-thin graphene sheets have unprecedented characteristics for biosensing applications. These characteristics include mechanical flexibility and strength, optical transparency, electrical sensitivity and biocompatibility. The primary theme of this dissertation is the characterization and application of graphene field-effect transistors (FETs) in biologically-relevant physiological environments.Understanding the interface that forms between an electrolyte and...
