Abstract

Gold nanodendrite (AuND) is a type of gold nanoparticles with dendritic or branching structures that offers advantages such as large surface area and high conductivity to improve electrocatalytic performance of electrochemical sensors. AuND structures can be synthesized using electrodeposition method utilizing cysteine as growth directing agent. This method can simultaneously synthesize and integrate the gold nanostructures on the surface of the electrode. We conducted a comprehensive study on the synthesis of AuND on screen-printed carbon electrode (SPCE)-based working electrode, focusing on the optimization of electrodeposition parameters, such as applied potential, precursor solution concentration, and deposition time. The measured surface oxide reduction peak current and electrochemical surface area from cyclic voltammogram were used as the optimization indicators. We confirmed the growth of dendritic gold nanostructures across the carbon electrode surface based on FESEM, EDS, and XRD characterizations. We applied the SPCE/AuND electrode as a nonenzymatic sensor on ascorbic acid (AA) and obtained detection limit of 16.8 μM, quantification limit of 51.0 μM, sensitivity of 0.0629 μA μM, and linear range of 180-2700 μM (R value = 0.9909). Selectivity test of this electrode against several interferences, such as uric acid, dopamine, glucose, and urea, also shows good response in AA detection.

摘要

金纳米枝晶 (AuND) 是一种具有树枝状或分支结构的金纳米粒子，具有较大的表面积和高导电性，可提高电化学传感器的电催化性能。AuND 结构可以通过利用半胱氨酸作为生长导向剂的电沉积方法合成。该方法可以同时在电极表面合成和集成金纳米结构。我们对基于丝网印刷碳电极 (SPCE) 的工作电极上的 AuND 合成进行了全面研究，重点优化了电沉积参数，如施加的电势、前体溶液浓度和沉积时间。循环伏安法测量的表面氧化还原峰电流和电化学表面积用作优化指标。我们通过 FESEM、EDS 和 XRD 特性确认了在整个碳电极表面生长的枝状金纳米结构。我们将 SPCE/AuND 电极用作抗坏血酸 (AA) 的非酶传感器，并获得了 16.8 μM 的检测限、51.0 μM 的定量限、0.0629 μA μM 的灵敏度和 180-2700 μM 的线性范围 (R 值= 0.9909)。该电极对尿酸、多巴胺、葡萄糖和尿素等几种干扰物的选择性测试也表明在 AA 检测中有良好的响应。
