Epinephrine (EP) is one of the important catecholamine neurotransmitters that play an important role in the mammalian
central nervous system. Therefore, it is necessary to determine the change of its concentrations. Nanoporous materials have
wide applications that include catalysis, energy storages, environmental pollution control, wastewater treatment, and sensing
applications. These unique properties could be attributable to their high surface area, a large pore volume, and uniform pore
sizes. A gold nanoporous layer modified gold electrode was prepared and applied for the selective determination of epinephrine
neurotransmitter at low concentration in the presence of several other substances including ascorbic acid (AA) and uric acid (UA).
The constructed electrode was characterized using scanning electron microscopy and cyclic voltammetry. The resulting electrode
showed a selective detection of epinephrine with the interferences of dopamine and uric acid over a wide linear range (from50
