The technology of electrochemical and biological nanosensors is a multidisciplinary combination of different sciences including biochemistry, molecular biology, chemistry, physics, electronics and computing. Nanosensors are used as efficient tools to identify biological molecules and have applications in various fields, such as medicine, food industry, production of pharmaceutical and health products. Chitosan is a chitinderived biopolymer that is non-toxic, biocompatible, bioactive and biodegradable. This biopolymer has outstanding properties and has the ability to form high quality films, making it widely used in the manufacture of sensors and biosensors. In this review, the use of chitosan as a platform for electrode surface modification in electrochemical sensors has been evaluated. Studies have shown that gold nanoparticles, graphene oxide, and carbon nanotubes can act as effective adsorbent materials for this electrode platform and improve the sensitivity, accuracy and stability of the sensors. The use of these modified platforms has been investigated for the detection of different molecules such as caffeine, gallic acid, melamine, glucose, etc. The results show that chitosan-based electrochemical and biosensors can be effectively used in the rapid and accurate detection of contaminants and biohazards in the food cycle. These technologies have advantages such as detection speed, accuracy, high sensitivity and reusability.
