(a) Parylene reaction scheme. (b) A schematic of the microelectrode fabrication process from a bare pipette to a final pyrolyzed microelectrode. A bare quartz pipette (far left) is coated with a thin layer of parylene C and subsequently pyrolyzed under an inert atmosphere. The pipette is then masked and insulated with another layer of parylene C to form a carbon electrode (far right). (c) Optical micrographs of pipettes at different stages of this process. From left to right: a bare pipette, a pipette after initial parylene C deposition, after pyrolysis of parylene C and a final parylene-insulated carbonaceous pipette.
