In this study, the development of a fast electroanalytical method for the characterization of wines through the evaluation of their phenolic content has been reported. A critical analysis of the influence of some experimental conditions on the efficient dispersion of carbon nanotubes (CNT) in water was carried out. The selected procedure consisted of: 1) 2.0 mg CNT were dispersed in 4.0 mL of 0.25...
The use of glassy carbon electrodes (GCEs) modified with multi-walled carbon nanotube (CNT) films for the continuous monitoring of polyphenols in flow systems has been examined. The performance of these modified electrodes was evaluated and compared to bare GCE by cyclic voltammetry experiments and by flow injection analysis (FIA) with amperometric detection monitoring the response of gallic, caffeic,...
