Abstract
En este trabajo, electrodos de carbón vítreo (GC) fueron modificados con nanotubos de carbono multipared
(CNT/GC) y se trataron electroquímicamente para obtener un material híbrido, CNT/material similar
al grafeno; que fue caracterizado mediante microscopía electrónica de barrido (SEM), espectroscopía
Raman, espectroscopía de energía dispersiva (EDS), y técnicas electroquímicas. Estos electrodos
modificados mostraron una capacidad electroquímica selectiva para la determinación de dopamina (DA)
y serotonina (5HT) en presencia de ácido ascórbico (AA) y ácido úrico (UA).

These modified electrodes showed selective electrochemical determination for dopamine (DA) and serotonin (5HT) in the presence of ascorbic acid (AA) and uric acid (UA).
