Abstract

A phosphopeptide-modified nanochannel was prepared based on a conical polymeric nanopore. It shows a reversible Ca2+-induced inactivation effect toward the ion flow and molecular transport, resulting from Ca2+ binding-caused surface charge neutralization and hydrophilicity reduction, and Ca2+ removal by the competitive binding.
