Electrochemical sensing of copper-chelator D- penicillamine based on complexation with gold nanoparticles modified copper based-metal organic frameworks

[Display omitted] •AuNPs@Cu-MOF was synthesized by a facile method.•It shows a good electro-catalytic activity towards D-PA determination.•D-PA is detected by the formation of complex at low potential.•The modified sensor shows wide linear range and low LOD.•The sensor was efficiently applied for ca...
