Electrochemical determination of morin in Kiwi and Strawberry fruit samples using vanadium pentoxide nano-flakes.

Herein, we report the synthesis of Vanadium Pentoxide Nanoflakes (VO NF) using ionic liquid and employed the VO NF in electrochemical determination of Morin (MR) in fruit samples. The VO NF were characterized by Powder X-ray diffraction (PXRD), scanning electron microscope (SEM), energy-dispersive X-ray analyzer (EDX), differential pulse voltammetry (DPV), and cyclic voltammetry (CV). Remarkably, the as-synthesized VO NF exhibited excellent electrochemical behavior and electrochemical ability towards MR. The CV and DPV studies were recognized that the electrochemical performance of VO NF film modified glassy carbon electrode (VO NF/GCE) towards detection of MR is outstanding in comparison with unmodified GCE. The proposed MR sensor shows a wide linear range, high sensitivity, and low limit of detection are 0.05-10.93μm, 1.130μAμMcm, and 9nM respectively. The fabulous analytical parameters of the developed sensor surpassed the previously reported modified electrodes, rendering the potential application of VO NF in environmental, biomedical, and pharmaceutical samples.
