Carbon Nanomaterial-Modified Microelectrodes

Carbon nanomaterials such as carbon nanotubes exhibit interesting physicochemical properties such as high specific surface area and high edge-to-basal graphitic ratio.  The Venton Lab explores the electrochemical properties of carbon nanomaterial-modified and carbon nanostructured electrodes to improved the sensitivity, temporal resolution, and antifouling properties for the FSCV detection of neurotransmitters.  Recently, we have characterized carbon nanospikes, carbon nanohorns, and carbon nanopipette electrodes.  Synthesis and characterization of carbon nanomaterials and modified electrodes are partially performed at the Center of Nanophase Materials Sciences, Oak Ridge National Lab.
