The anodization of aluminum is an electro-chemical process that changes the surface chemistry of the metal, via oxidation, to produce an anodic oxide layer. During this process a self organized, highly ordered array of cylindrical shaped pores can be produced with controllable pore diameters, periodicity and density distribution. This enables anodic aluminum oxide (AAO) membranes to be used as templates in a variety of nanotechnology applications without the need for expensive lithographical techniques. This review article is an overview of the current state of research on AAO membranes and the various applications of nanotechnology that use them in the manufacture of nano-materials and devices or incorporate them into specific applications such as biological/chemical sensors, nano-electronic devices, filter membranes and medical scaffolds for tissue engineering.

铝的阳极氧化是一种电化学过程，通过氧化改变金属的表面化学性质，以产生阳极氧化层。在此过程中，可以产生具有可控孔径、周期性和密度分布的自组织、高度有序的圆柱形孔阵列。这使得阳极氧化铝（AAO）膜能够在各种纳米技术应用中用作模板，而无需昂贵的光刻技术。这篇综述文章概述了AAO膜的当前研究状况以及纳米技术的各种应用，这些应用在纳米材料和器件的制造中使用AAO膜，或将其纳入特定应用，如生物/化学传感器、纳米电子器件、滤膜和用于组织工程的医用支架。
