dc.description.abstractA gold nanoparticle-modified PVC/TTF-TCNQ composite electrode with tyrosinase enzyme is proposed as electrochemical biosensor for detecting phenolic compounds in musts and wines samples using phenol and catechol as standards. The work potential was 0 V both in batch and in FIA system (linear range from 0.6 μM up to 10.0 μM), with a detection limit of 7.9 x 10-7 M for phenol and 6.43 x 10-7 M for catechol. The good correlation between the results obtained with the biosensor and those achieved with the Folin–Ciocalteu reference method enables that it can be used for rapid and almost automated estimation of the “total phenolics” and “high antioxidant” fraction of must and commercial wines.es_ES
