Abstract
A nanomachined and micromachined electrode () is disclosed that is produced by providing a layer of aluminum () positioned upon a conductive substrate (), anodizing the layer of aluminum to produce a layer of aluminum oxide () having an array of pores (), depositing a sacrificial metal () within the pores of the aluminum oxide layer, etching the aluminum oxide layer so as to leave an array of sacrificial metal rods (), depositing a layer of electrode material () between the array of sacrificial metal rods, and etching the sacrificial metal rods so that a layer of copper remains having an array of pores () where the sacrificial metal rods had existed. The layer of copper is the electrode ().
