摘要

Fullerene Black (FB) and Extracted Fullerene Black (EFB) were used in modified screen-printed electrodes producing electrochemical transducers (FB-SPEs and EFB-SPEs). A complete electrochemical study was performed and the best results are obtained working with FB-SPEs, especially in terms of: 1. improved electron-transfer kinetic mechanisms and 2. sensitivity and selectivity toward Acetaminophen (Ac) and Guanine (G). These latter represent two important electro-active targets to quantify in medicine field application, because: Ac is a preferred alternative (as analgesic-antipyretic agent) to aspirin, particularly for patients who cannot tolerate aspirin; the oxidation signal of G is useful for the fabrication of emerging analytical tools, such as DNA chipsand user-friendly diagnostic devices. Ac and G are quantify by using FB-SPEs electrochemical devices, with an extended linearity (1-300M for Ac; 0.1-300M for G), an excellent sensitivity (2.82AM(-1)cm(-2) in the case of Ac; and 0.183AM(-1)cm(-2) in the case of G), a low detection limit (0.01M for Ac; 0.005M for G), a very good reproducibility (both: intra-; inter-electrodes reproducibility RSD % ranging from 0.3-0.5 for Ac; and 0.50-0.85 for G) and a very fast response time (6s for Ac; 5s in the case of G). In addition, high selectivity is obtained at FB-SPEs, meaning that the FB-SPEs electrochemical transducers are suitable to simultaneously quantify Ac and G in real samples, having several different (highly concentrated) interference.
