Nonenzymatic Electrochemical Glucose Biosensor Based on Ionic Liquid and Nickel Nanoparticles
A nonenzymatic electrochemical biosensor based on ionic liquid (IL) and nickel nanoparticles (NiNPs) for the detection of glucose was investigated in this study. The morphologies of NiNPs and composite of IL and NiNPs were characterized by using scanning electron microscopy. The IL-NiNPs composite showed high electrocatalytic activity for the oxidation of glucose in alkaline solution. The fabricated biosensor exhibited excellent performance for glucose determination with a wide linear range (0.1–20 mmol/L) and a detection limit of 0.03 mmol/L.
