Abstract

In this study, we investigated the electrochemical modification of a gold electrode using poly(L-phenylalanine) and its applicability for the quantification of resveratrol (RESV). The gold electrode was modified with L-phenylalanine employing cyclic voltammetry (CV) in aqueous solution. The detection of RESV with the modified electrode was investigated by square wave voltammetry (SWV) in a phosphate buffer solution (PBS) (pH = 1.2). The analytical calibration curve for RESV showed a linear response with concentration in the oxidation peak current range from 50 to 1000 µM, with a limit of detection (LOD) of 35.16 µM and limit of quantitation (LOQ) of 105.5 µM. The application of the prepared electrochemical sensor was carried out with a standard addition method in red wine samples.

聚l-苯丙氨酸修饰金电极伏安法测定白藜芦醇

在本研究中，我们研究了聚L-苯丙氨酸对金电极的电化学修饰及其在白藜芦醇（RESV）定量中的适用性。采用循环伏安法对金电极进行了L-苯丙氨酸修饰。在磷酸盐缓冲溶液（PBS）（pH=1.2）中，通过方波伏安法（SWV）研究了修饰电极对RESV的检测。RESV的分析校准曲线显示，在50至1000µM的氧化峰值电流范围内，浓度呈线性响应，检测限（LOD）为35.16µM，定量限（LOQ）为105.5µM。采用标准加入法对所制备的电化学传感器在红酒样品中的应用进行了研究。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
