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