Abstract

Food safety monitoring is of paramount significance to protect consumers and to assure the efficient operation of several industrial processes. Nanobiosensors hold considerable promise for the quantitative detection of food contaminants with reduced analysis times, negligible sample preparation, expeditiousness, and high sensitivity and selectivity. This chapter aims to cover recent progress in the development of nanobiosensors for food safety and control monitoring. First, a brief overview of the design of nanobiosensors, with special emphasis on the nanomaterials used for their construction, will be given. Secondly, examples of different nanobiosensors for food safety assurance and control, classified according to the transduction mechanism (electrochemical, optical, or mechanical nanobiosensors) will be extensively covered. To conclude, future prospects and directions will be discussed.
