Original Abstract

A simple electroanalytical procedure has been developed for the determination of polyamine spermine using the ZnONPs-MWCNTs-CPE sensor. Spermine has been irreversibly oxidized on a modified electrode at a potential of +0.92 V versus Ag/AgCl (KCl, 3.5 mol L-1). The developed sensor demonstrated a respective linear response in borate buffer pH 8.5 from 2 mu mol L-1 to 100 mu mol L-1, with a detection limit of 0.300 mu mol L-1 and quantification limit of 0.998 mu mol L-1. The proposed sensor showed high reproducibility (RSD = 2.58 %), stability, robustness, and no obvious interference effects of several inorganic ions and organic molecules. The obtained results demonstrated excellent performance during the determination of the spermine in human urine samples with satisfactory recovery results (98.41-101.34 %), offering promising opportunities for practical clinical analysis.
