An electrochemical sensor was prepared by modifiying a hybrid
of multi-walled carbon nanotubes (MWCNTs) and zinc oxide nanoparticles (ZnONPs)
to a glassy carbon (GC) electrode surface to accurately determine agmatine. The
ZnONPs+MWCNTs/GC electrode surface was characterized using scanning electron
microscopy and energy dispersive X-ray. Agmatine did not exhibit any peak on
the GC electrode surface but exhibited a large oxidation peak at 637.9 mV
on the MWCNT/GC electrode surface. Furthermore, it was observed that the
electrochemical behavior of agmatine was greatly improved on the
MWCNT+ZnONPs/GC electrode surface and that this surface exhibited a
well-defined higher current peak at 581.9 mV. The electrochemical
responses of agmatine on the MWCNT+ZnONPs/GC electrode surface were performed
using square wave voltammetry. A linear plot was obtained for the
current responses of agmatine against concentrations in the range of 0.1 µM–5.2 µM yielding a detection limit
of 4.13×10−6 M (based on 3Sb/m). The accurate
quantification of agmatine makes the ZnONPs+MWCNTs/GC electrode system of great
interest for the
treatment of schizophrenia.
