Research Progress of Hydrogels-Based Materials and Their Application for Electrochemical Sensing of Hazardous Substances in Foods

Abstract

Due to the advantages of large surface area, easy functional structure, good biocompatibility, and easy integration into signal transduction system, hydrogel-based nanocomposite is an excellent electrode modification material. Several common synthesis strategies of hydrogel-based nanocomposites and their significance as electrochemical modified electrode materials were summarized in this paper. The preparation of hydrogel-based nanocomposites modified electrode and their sensing mechanism for the electrochemical detection were discussed. Finally, the preparation of hydrogel-based nanocomposites and their applications in electrochemical sensors are summarized and prospected, which will have importance to promote the development of electrochemical sensing detection technology.
