Abstract: In this work, a modified 3D-rGO/MWCNT with nickel and copper oxide nanoparticles were synthesized.
The structural properties of this nanocomposite were investigated by several techniques. The fabricated sensor
at optimum condition potential of +0.60 V (vs. Ag/AgCl) and a rotational rate of 1800 rpm gave a detection limit of
0.04 μmol L-1 with two dynamic ranges of 0.10–300 and 300–900 μmol L-1 glucose with high stability. The good
accuracy of the fabricated sensor was proved in the determination of glucose in a blood sample (with recoveries
between 95% to 105% and RSDs of 1.2 to 2.5%).
