We report a very simple and novel approach to produce anodic TiO 2 nanotube arrays with highly defined and ordered tube openings. It is based on carrying out anodization through a slowly soluble photoresist coating. This eliminates the formation of undesired initiation layers on the tube tops and protects them to a certain extent from etching by the electrolyte.(© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
