Artificial single nanochannels with chemical/structural asymmetry and controllable continuous change of ionic‐current rectification are prepared by ion‐sputtering technology. The nanochannel is embedded in a track‐etched poly(ethylene terephthalate) (PET) membrane and sputtered with Pt on the tip side of the nanochannel.
