通过两步复制阳极多孔氧化铝的蜂窝结构，制备了高度有序的金属纳米孔阵列（铂和金）。制备多孔氧化铝的负多孔结构，然后与金属形成正结构，得到蜂窝金属结构。该膜的金属孔阵列具有均匀的、紧密堆积的蜂窝结构，直径约为70纳米，厚度为1至3微米。由于其纹理化的表面，金的金属孔阵列与块金相比显示出显著的颜色变化。
A highly ordered metal nanohole array (platinum and gold) was fabricated by a two-step replication of the honeycomb structure of anodic porous alumina. Preparation of the negative porous structure of porous alumina followed by the formation of the positive structure with metal resulted in a honeycomb metallic structure. The metal hole array of the film has a uniform, closely packed honeycomb structure approximately 70 nanometers in diameter and from 1 to 3 micrometers thick. Because of its textured surface, the metal hole array of gold showed a notable color change compared with bulk gold.
