Abstract In this study, highly catalytic platinum nanoparticles (PtNPs) were synthesized on polished Au thin-film electrode using surfactant assisted electrochemical technique (SAET) for a high-performance non-enzymatic glucose sensor. Residual surfactants on the fabricated electrodes were removed by dipping into a tetrahydrofuran (THF) solution. The physical characteristics of the electrodes were investigated through FESEM, XRD, and EDX, and the analytical analyses were demonstrated with cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and amperometry. After optimization considering the NP deposition potential and time, dipping time in THF, the fabricated biosensor showed a promising electro-oxidation towards glucose in terms of high sensitivity of 5.87 ± 0.13 μAmM−1 cm−2, detection limit of 0.235 μM, wide linear range from 0.25–36 mM, fast response lower than 5 s, and good reproducibility and stability. The proposed SAET can be applied to uniform deposition and dispersion of other nanoparticles for numerous applications. Therefore, the proposed sensing platform can be useful to monitor glucose in diagnostic bioprocess monitoring and environmental monitoring.

摘要 在这项研究中，使用表面活性剂辅助电化学技术 (SAET) 在抛光的 Au 薄膜电极上合成了用于高性能非酶促葡萄糖传感器的高催化铂纳米粒子 (PtNPs)。通过浸入四氢呋喃 (THF) 溶液中去除所制造电极上残留的表面活性剂。通过 FESEM、XRD 和 EDX 研究了电极的物理特性，并通过循环伏安法 (CV)、电化学阻抗谱 (EIS) 和电流分析法证明了分析分析。在考虑 NP 沉积电位和时间、在 THF 中的浸渍时间进行优化后，制造的生物传感器在 5.87 ± 0.13 μAmM-1 cm-2 的高灵敏度、0.235 μM 的检测限方面显示出对葡萄糖的有希望的电氧化，0.25-36 mM 的宽线性范围，低于 5 s 的快速响应，以及良好的重现性和稳定性。所提出的 SAET 可以应用于其他纳米粒子的均匀沉积和分散，以用于多种应用。因此，所提出的传感平台可用于在诊断生物过程监测和环境监测中监测葡萄糖。
