Abstract

•Net currents with zero-average time dependent potentials in single nanopores•Results reminiscent of those found in electrochemical ratchet systems•Applications in bio-electrochemistry and pH sensing and regulation•Potential interest in chemical processors and energy conversion in liquid state

We have studied experimentally and theoretically the rectifying properties of a single asymmetric nanopore functionalized with amphoteric lysine groups and characterized the net current obtained with zero-average time dependent potentials. The pH-controlled rectification phenomena may be relevant to bio-electrochemistry, pH sensing and regulation, and energy conversion.
