    We report a label-free nanopore sensor for the detection of Zn 2+ ions. By taking advantage of the cleavage of a substrate peptide by zinc-dependent enzymes, nanomolar concentrations of Zn 2+ ions could be detected within minutes. Furthermore, structurally similar transition metals such as Ni 2+ , Co 2+ , Hg 2+ , Cu 2+ , and Cd 2+ did not interfere with their detection. The enzymatic reaction-based nanopore sensing strategy developed in this work may find potential applications in environmental monitoring and medical diagnosis.
