A highly sensitive electrochemical method, based on a gold nanoparticle (GNP)-modified indium tin oxide (ITO) electrode (ITO/GNP), was developed for the detection of amoxicillin (AMX). Amoxicillin was adsorbed onto ITO/GNP to prepare ITO/GNP/AMX electrode, which was further modified with Cu(II) by simple dropping of Cu(II) solution. The modified electrodes were characterized by scanning electron microscope (SEM) and electrochemical methods. Amoxicillin was detected by using anodic peak current of Cu in square wave voltammetry (SWV). A linear concentration range from 10 to 1000 nM with a detection limit of 0.5 nM for amoxicillin was found.
