Application progress of nanobiosensors in food analysis

Nowadays, food industry is the key field of nanobiosensors application. Functional nanomaterials can be used as catalyst, immobilization platforms or optical labels, to improve the bio-sensing performance to exhibit higher sensitivity, stability, and selectivity. Nanomaterials, such as metal nanoparticles, nanocomposite, magnetic nanoparticles, nanowires, carbon nanotubes, nanorods and quantum dots are playing an important role in nanobiosensors, especially in food detection. This study reviewed the application and development of nanobiosensors in food analysis, especially in the detection of pesticides, pathogens, and sugar. The nanobiosensors system is helpful for develop high sensitivity, strong applicability, convenient and fast food testing techniques and methods.
