Nanomaterial-Based Electrochemical Sensors for Highly Sensitive Detection of Foodborne Pathogens

Abstract

In this chapter we briefly survey the main foodborne pathogens in terms of their causes, symptoms and impact on human health. We have described the principles of detection for some important analytes by conventional means and by electrochemical biosensors using either immunoassay or nucleic acid assay. We provide a survey of the use of nanomaterials in such biosensors, both in terms of the possible electrode modifications that are available to increase the sensor response, and in terms of how nanomaterials can be used to construct labels for electrochemical biosensors.
