Voltammetric determination of amoxicillin using gold nanoparticles modified glassy carbon electrode

Amoxicillin (AMX) is one of the most frequently used β-lactam antibiotics in the world. Because of therapeutic importance, development of rapid and sensitive methods for clinical monitoring of AMX are important [1]. Different analytical techniques have been applied for determination of AMX such as HPLC [2] and voltametric methods [3-5]. The HPLC method have been often time consuming processes and are usually expensive. In this study, a novel modified electrode is prepared by electrochemical deposition of nano‐Au on the surface of a poly(L‐methionine) (PMT)‐modified glassy carbon electrode (GCE). The nano‐Au/PMT/GCE was used as a novel sensor for determination of AMX in biological sample.
