An array of micro/nanoelectrodes offers most of the advantages of single micro/nanoelectrodes, but with the added benefit of a higher total current output and increasing sensitivity. This work reports the analytical performance of a gold electrode modified with a Mn(III) porphyrin nanobar-film (NBMn-PPh) employed for the sensitive determination of Ascorbic Acid (AA) at pH = 7.4 in the presence of always coexistence interferences Dopamine (DA) and Uric Acid (UA).
