An electrochemical sensing platform was developed based on the magnetic loading of carbon nanotube (CNT)/nano-Fe 3 O 4 composite on electrodes. To demonstrate the concept, nano-Fe 3 O 4 was deposited by the chemical coprecipitation of Fe 2+ and Fe 3+ in the presence of CNTs in an alkaline solution. The resulting magnetic nanocomposite brings new capabilities...
A novel, stable and highly sensitive non-enzymatic glucose (Glc) sensor was developed using vertically well-aligned multi-walled carbon nanotubes array (MWCNTs) incorporated with cupric oxide (CuO) nanoparticles. The MWCNTs array was prepared by catalytic chemical vapor deposition on a tantalum (Ta) substrate, while a simple and rapid two-step electrodeposition technique was used to prepare the CuO–MWCNTs...
A novel glucose biosensor based on the chemiluminescence (CL) detection of enzymatically generated H 2 O 2 was constructed by the effective immobilization of glucose oxidase (GOD)/carbon-nanotubes (CNTs)/gold nanoparticles (GNPs) in nafion film on graphite support. The influences of various experimental parameters such as solution pH, the action time of the enzyme, interferents and...
