NiO Nanoflowers for Non-Enzymatic Amperometric Detection of Glucose

and a limit of detection of 10 µM. The results show that the linear range of detection increases while the sensitivity decreases with an increase in the loading mass of the nanomaterial after a certain loading concentration. In addition, the electrodes showed high selectivity towards glucose in the presence of other interfering species, such as ascorbic acid, fructose, sucrose, and NaCl. The impact of loading concentration on the selectivity of NiO NF-modified electrodes shows a decrease in selectivity with the increase in loading of the nanomaterial after a certain optimal loading mass.
