Research data for article: PEGylated network nanostructured by gold nanoparticles for electrochemical sensing of aromatic redox and nonredox analytes

The design, tailoring, and physicochemical properties of a multicomponent polyethylene glycol (PEG)-based polymer doped with spherical nanoparticles modified with a lipoic acid derivative of cyclodextrin and its application for the electrochemical sensing of a ferrocene derivative and ibuprofen at low concentrations is presented. Such a composition increases the analytical performance of the sensor, supports further improvement of the detection limit, and enables the determination of the analyte after saturation of cyclodextrin cavities (high concentration of analyte) based on its diffusion response. The designed hybrid material was used for the direct and indirect determination of aromatic analytes─ferrocene derivative and ibuprofen─with very low detection limit.
