Abstract
With the rapid development of the food industry, food safety has received more and more attention from various countries. There are many factors affecting food safety, among which foodborne pathogens are one of the main factors. Therefore, it is becoming more and more important to develop rapid detection methods for foodborne pathogens. Biosensors have the advantages of simplicity, small size, low cost, high sensitivity, strong specificity, strong anti-interference ability, and quick response. To better understand the roles of biosensors in the detection of foodborne pathogens, this review focuses on latest development of pathogens rapid detection with biosensors. We introduced three types biosensors including optical, electrochemical, mass sensitive biosensors and discussed the application of nanobiotechnology in biosensors. We found that the optical and electrochemical biosensors have been studied for quite periods of time, therefore their better performance is accepted and appreciated during commercialization. Beyond that, monitoring viable cells are of great importance for food quality control and people's health supervision. We believe that the potential of various biosensors may shed new light on viable cell measurement and counting in the future.
