Abstract

In this study, silver nanoparticles (Ag NPs) were synthesized in biogenic methods. It is aimed to improve the electrochemical sensor efficiency of synthesized Ag NPs against the pharmaceutical drug paracetamol. For this purpose, fourier transmission infrared spectroscopy (FTIR), ultra-violet visible spectroscopy (Uv–vis), X-ray differentiation (XRD), and transmission electron spectroscopy (TEM) analyses were performed to elucidate the structure of the synthesized Ag NPs. In the TEM characterization results, the mean size of the NPs was found to be 19.035 nm using TEM characterization and the XRD results, the crystalline size of the NPs was 11.66 nm. Sensor studies were performed with cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. Paracetamol showed a sensitivity of approximately 0.4 V to Ag NPs in this study. The linear ranges of this study are 6.5–14.5 µM, with a limit of detection (LOD) of 5.79 µM and a limit of quantification (LOQ) of 17.56 µM.

用生物方法合成纳米银颗粒：药物扑热息痛传感器的表征与开发

本研究采用生物方法合成了银纳米粒子（Ag NPs）。目的是提高合成的银纳米粒子对药物扑热息痛的电化学传感器效率。为此，对合成的 Ag NPs 进行了傅立叶透射红外光谱（FTIR）、紫外可见光谱（Uv-vis）、X 射线分光（XRD）和透射电子显微镜（TEM）分析，以阐明其结构。在 TEM 表征结果中，发现 NPs 的平均尺寸为 19.035 nm；在 XRD 表征结果中，发现 NPs 的结晶尺寸为 11.66 nm。利用循环伏安法（CV）和微分脉冲伏安法（DPV）技术进行了传感器研究。在这项研究中，扑热息痛对 Ag NPs 的灵敏度约为 0.4 V。该研究的线性范围为 6.5-14.5 µM，检测限 (LOD) 为 5.79 µM，定量限 (LOQ) 为 17.56 µM。

期刊介绍： Topics in Catalysis publishes topical collections in all fields of catalysis which are composed only of invited articles from leading authors. The journal documents today’s emerging and critical trends in all branches of catalysis. Each themed issue is organized by renowned Guest Editors in collaboration with the Editors-in-Chief. Proposals for new topics are welcome and should be submitted directly to the Editors-in-Chief. The publication of individual uninvited original research articles can be sent to our sister journal Catalysis Letters. This journal aims for rapid publication of high-impact original research articles in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
