Electrochemical immunosensors, genosensors and phagosensors for Salmonella detection

Abstract

This review discusses the current state of the art Salmonella detection methods. In this perspective, emphasis is given to the recent developments in biosensors, in particular electrochemical immunosensors, genosensors and phagosensors. Different aspects of biosensors development have been summarised and discussed in detail. The integration of new materials into biosensors such as magnetic particles is also fully revised. More importantly, the advantages of using magnetic particles in magnetic separation of bacteria coupled with different detection techniques are also reviewed. This article also deals with the latest developments in simultaneous detection of several foodborne pathogenic bacteria. Accordingly, research opportunities and future development trends in these areas are finally discussed.
