Trois-Dimensional Au / Holey-Graphene comme interface électrochimique efficace pour la détermination simultanée de l'acide ascorbique, de la dopamine et de l'acide urique.

La quantification de l'acide ascorbique (AA), de la dopamine (DA) et de l'acide urique (UA) a été un domaine de recherche important, car la détermination de ces molécules correspond directement au diagnostic et au contrôle des maladies de la physiologie nerveuse et cérébrale. . Dans notre étude, l'oxyde de graphène (GO) avec des nanopores déposé avec des nanoparticules d'or a été auto-assemblé pour former des structures composites tridimensionnelles (3D) Au / oxyde de graphène (Au / HGO). Les structures composites 3DAu / HGO telles que préparées ont été caractérisées par diffraction des rayons X, spectre Raman, microscopie électronique à balayage et microscopie électronique à transmission couplée à des voltamogrammes cycliques. Enfin, le 3DAu / HGO proposé présente une sensibilité élevée, d’excellentes propriétés de transport d’électrons et une sélectivité pour la détermination électrochimique simultanée de AA, DA et UA avec des plages de réponse linéaire de 1,0 (-) 500 muM, 0,01 (-) 50 muM et 0,05 ( -) 50 muM respectivement. Cette découverte ouvre la voie aux applications du graphène en tant que biocapteur pour la détection de trois analytes dans le sérum humain.
