approaches for the preparation of such systems is templatedelectrodeposition. In the present study, porous anodic alumina templates are used to prepare Au nanoelectrode arrays. Multistage electrodeposition is proposed for the formation of recessed electrodes with the ability to tune the distance between the
pathways to further improve the recessed nanoelectrode arrays based on anodic alumina templates are discussed.

A nanoelectrode array (NEA) is a set of regularly arranged isolated metal
available porous AAO films with a highly irregular structure to prepare the Au nanowell electrodes with 600 nm depth by templatedelectrodeposition. It is worth noting that the percentage of nanoelectrodes in the array that are involved in electrochemical reactions has not been discussed in detail. At the
