Evaluation of a Non-Enzymatic Electrochemical Sensor Based on Co(OH)-Functionalized Carbon Nanotubes for Glucose Detection.

This work reports on the assessment of a non-hydrolytic electrochemical sensor for glucose sensing that is developed using functionalized carbon nanotubes (fCNTs)/Co(OH). The morphology of the nanocomposite was investigated by scanning electron microscopy, which revealed that the CNTs interacted with Co(OH). This content formed a nanocomposite that improved the electrochemical characterizations of the electrode, including the electrochemical active surface area and capacitance, thus improving sensitivity to glucose.

Electrochemical Sensor for Hydrogen Peroxide Based on Prussian Blue Electrochemically Deposited at the TiO-ZrO-Doped Carbon Nanotube Glassy Carbon-Modified Electrode.

In this investigation, a hydrogen peroxide (HO) electrochemical sensor was evaluated. Prussian blue (PB) was electrodeposited at a glassy carbon (GC) electrode modified with titanium dioxide- and zirconia-doped functionalized carbon nanotubes (TiO.ZrO-fCNTs), obtaining the PB/TiO.
