AB This work shows the potential of modified screen-printed carbon electrodes (SPCEs) for sensitive and selectivedetection of 4-ethylphenol in wine. Gold nanoparticles (AuNPs) and fullerene C60 (C60), modified sensors havebeen compared. pH of the supporting electrolyte, deposition time and working temperature have been optimizedconsidering their influence in the voltammetric pulse response of 4-ethylphenol. Under the optimal conditions ofmeasurement, the developed activated C60/SPCE (AC60/SPCE) shows the best performance, with a detectioncapability of 400 μg/L and 700 μg/L, when using deposition times of 14 min and 6 min, respectively (α = β =0.05). The reproducibility of the developed sensor resulted better when a deposition time of 6 min was used (5.4%, n = 3). The influence of different interferents on the analytical response has been studied, as well as theirapplication in the determination of 4-ethylphenol in different wine samples.
