Lateral flow based immunobiosensors for detection of food contaminants

Abstract

Safety of food is of great concern these days due to various contaminations including toxins, infectious agents and chemical contaminants. Therefore, there is a need to develop promising and user's friendly method to monitor food safety. Lateral flow tests are new, simple and rapid alternative for detection of food-borne pathogens compared with traditional methods. In this review article, we surveyed application of lateral flow biosensors in detection of different food contaminants and labels used to enhance the efficiency of the system. Finally, the unique feature of multi-parametric analysis of analytes by lateral flow device has been reported, proving a lateral flow system is able to be designed in a way to detect multiple targets, simultaneously.
