Abstract
By grafting specific response DNA on the interior surface of ion track-etched conical nanochannels, a highly sensitive and selective ionic gate that can be driven by silver (I) ions is demonstrated. The switches between the OFF-state and the ON-state are mainly dependent on silver (I) ions and cysteine. Such a biomimetic nanodevice shows potential for application in sensing, pharmaceuticals, and sterilization.Entities:
