عنوان انگلیسی A Sensitive Electrochemical Sensor Due to Novel Bionanocomposite to Determine Tartrazine
چکیده انگلیسی مقاله The novel composite was fabricated utilizing gold nanoparticle-modified (AuNPs) reduced graphene oxide composite and acetone-extracted propolis (AEP) for electrochemical sensors on screen-printed electrodes (AuNPs/rGO/AEP/SPE) using electrochemical approaches for Tartrazine (Tz) detection. Acetone-extracted Propolis (AEP) was provided for the first time and a facile route were suggested to synthesize AuNPs-loaded functionalized rGO detect Tz. Electrochemical experiments and scanning electron microscopy (SEM) were applied for electrode characterization. The diagrams of provided cyclic voltammetry (CV) indicated that the highest Tz oxidation catalytic activity was provided for AuNPs/rGO/AEP/SPE followed by rGO/AEP/SPE, GO/AEP/SPE and SPE. Utilizing differential pulse voltammetry (DPV) technique in the range of 0.004 to 2 µM with a detection limit of 3 nM, the range for Linear Tz calibration curves were provided at AuNPs/rGO/AEP/SPE. The findings of this study showed that AuNPs/rGO/AEP/SPE could be applied for Tz detection with high stability, low detection limit and high sensitivity, which appear to be helpful to manufacture the portable sensors in the food industry.
