Sample Text
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 mu M, with a limit of detection (LOD) of 35.16 mu M and limit of quantitation (LOQ) of 105.5 mu M. The application of the prepared electrochemical sensor was carried out with a standard addition method in red wine samples.
