Abstract:

Electrodes having tip diameters in the few hundred nanometer range have been constructed by coating thin copolymer films onto suitable electrode materials that have been etched to very small dimensions. Desorption of the insulation from the exact tip of the structure is a key element in the construction of electrodes of suitable dimensions for neuronal analysis. Preliminary data obtained in collaboration with Yau Yi Lau of our laboratories shows the utility of these insulated, etched carbon fiber electrodes for analysis of neurotransmitter release from single nerve cells. js
