Reduced graphene oxide nanocomposite based electrochemical biosensors for monitoring foodborne pathogenic bacteria: A review

Abstract

Foodborne disease poses an enormous threat to the safety of human beings all over the world. The rapid and accurate monitoring and determination of foodborne pathogenic bacteria is of great significance to food safety. In recent years, with the evolution of nanotechnology, reduced graphene oxide (rGO) nanocomposites have been frequently introduced into the construction of electrochemical biosensors due to their unique physicochemical properties and biocompatibility. The combination of biomolecules with specific recognition capabilities and rGO nanocomposites provide a promising strategy to construct more stable and sensitive electrochemical biosensors for the detection of foodborne pathogenic bacteria. This review tracks the development of rGO nanocomposite materials electrochemical biosensors for the detection of foodborne pathogenic bacteria, mainly including the preparation of rGO nanocomposite electrochemical biosensors and their working mechanism. The challenges in this field are discussed, and a perspective for further development is proposed, with the goal of promoting development of sensing technology for foodborne pathogenic bacteria to help prevent outbreaks of foodborne disease.
