The nanochannel (in a porous layer) and ion‐channel (in a barrier layer) hybrid structure of anodic alumina is used as a protein‐trapping device. The transmembrane potential drives the electromigration of the charged proteins (FITC‐labeled) into the nanochannels, but electromigration across the barrier layer is impossible due to the size‐exclusion effect. As a result, the proteins can be continuously trapped in the nanochannels.
