148 They used PDMS microchannels to guide single pheochromocytoma PC12 cells into a chamber etched into glass. When this cell was stimulated with nicotine, they could detect dopamine release by amperometric monitoring using a carbon fiber microelectrode. 151 They recorded amperometric spikes using indium tin oxide (ITO) electrodes when the catecholamines were oxidized on the electrode surface. When trying to differentiate the complex interactions that occur between different cells in mixed-type or pure-type cultures, it is important to determine the cell’s chemical response to stimulation, in addition to its electrical and morphological responses.
