Non-Enzymatic Glucose Biosensor Based on CuO-Decorated CeO(2) Nanoparticles

Copper oxide (CuO)-decorated cerium oxide (CeO(2)) nanoparticles were synthesized and used to detect glucose non-enzymatically. The morphological characteristics and structure of the nanoparticles were characterized through transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ra...

description Copper oxide (CuO)-decorated cerium oxide (CeO(2)) nanoparticles were synthesized and used to detect glucose non-enzymatically. The morphological characteristics and structure of the nanoparticles were characterized through transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. The sensor responses of electrodes to glucose were investigated via an electrochemical method. The CuO/CeO(2) nanocomposite exhibited a reasonably good sensitivity of 2.77 μA mM(−1)cm(−2), an estimated detection limit of 10 μA, and a good anti-interference ability. The sensor was also fairly stable under ambient conditions.
