A hydrothermally prepared reduced graphene oxide-supported copper ferrite hybrid for glucose sensing
Source abstract
Abstract
Abstract A stable enzyme-free glucose sensor was fabricated via a facile in situ hydrothermal route by the formation of CuFe 2 O 4 nanoparticles into the graphene oxide sheets. The contents of graphene oxide in composites were varied from 10 to 30 wt%. The morphology of formed CuFe 2 O 4 /rGO nanocomposite was found by TEM analysis. The electrocatalytic activity of different CuFe 2 O 4 /rGO samples towards glucose oxidation was studied by employing cyclic voltammetry and chronoamperometry techniques. CuFe 2 O 4 /rGO(30 wt%) sample showed the highest oxidation current. An excellent sensitivity value of 1824.22 μA mM −1 cm −2 with a detection limit of 1.0 μM was gained by CuFe 2 O 4 /rGO(30 wt%). The sensor also exhibits good reproducibility and long term stability as well as high selectivity with insignificant interference from ascorbic acid and uric acid.
