Electrochemical sensing of sulfate in aqueous solution with a cyclopeptide-dipyrromethene-Cu(II) or Co(II) complex attached to a gold electrode

[Display omitted] •Anion-binding cyclopeptide was immobilized on a gold surface via (bis)dipyrromethene metal complexes.•Anion sensing relies on the combination of a redox center and an anion receptor.•Lack of the necessity of using the external redox marker.•Sensors allow the sensitive detection of...
