Electrochemical detection of adenine and guanine using a self-assembled copper(<scp>ii</scp>)–thiophenyl-azo-imidazole complex monolayer modified gold electrode

Abstract

A self-assembled copper(<sc>ii</sc>)–thiophenyl-azo-imidazole complex monolayer modified gold electrode exhibits an excellent electrochemical sensing ability towards adenine and guanine at physiological pH.
