摘要：

An amperometric electrode based on multiwall carbon nanotubes (MWCNTs) and Fe nanoparticles (NPs) has been successfully fabricated. The electrode combined with Flow Injection Analysis (FIA) exhibits linear response in the concentration range of 0.1-12 mu M and the sensitivity of 30.0 nA mu M-1 for most of amino acids, confirming good complexation of amino acids (AAs) with Fe NPs on the modified electrode. The determination of 17 amino acids in the hypothalamus microdialysis fluids of guinea pigs, illustrates that it is a powerful tool to investigate physiology and pathology mechanisms.
