In this paper , anodic aluminum oxide films form globally self‐aligned and locally self‐organized order nanochannels with characteristic diameter/spacing and unmatched aspect ratio. The range of order can be increased tremendously by various lithographic guiding methods. Focused ion beam can selectively close individual nanochannels to fabricate arrays with custom‐designed geometry, which can be exploited to create arrays of nanochannels with different diameters after subsequent chemical etching. By controlling the anodization voltage to change the characteristic diameter/spacing, nanochannles can be bended and enlarged to change their longitudinal geometry, forming arrays with fascinating 3‐dimensional architecture. More details about this figure will be discussed by Prof. Yuh‐Lin Wang and his co‐workers on page 11~24 in this issue.
