Introduction: Nanoelectrode ensembles (NEEs) are nanotech-based electroanalytical tools that ﬁnd application in a variety of ﬁelds ranging from electroanalysis to sensors and electronics. The NEEs are fabricated by growing metal nanowires in the pores of a template microporous membrane. The density of the pores in the template determines the number of nanoelectrode elements per surface unit and the average distance between the nanoelectrode elements. The preparation of nanoelectrode using microporous membranes as templates distinguishes itself for its simplicity and wide applicability. .
