Application of electrochemical biosensors for detection of food pathogenic bacteria

Abstract

Current practices for preventing microbial diseases rely upon careful control of various kinds of pathogenic bacteria in food safety and environmental monitoring. The main disadvantages of conventional bacterial detection methods are the multistep procedure and long time requirements. This article gives an overview of alternative electrochemical biosensors for detection of pathogenic bacteria in the food industry. Focus has been on new microbial metabolism-based, antibody-based and DNA-based biosensors. The underlying principles and applications of these biosensors are discussed. Recent developments in flow-injection biosensor systems with an electrochemical detection are also presented.
