Chitosan is a biodegradable natural polymer with wide applications in the fields of medicine and agriculture. Through modification and other configurations, the range of chitosan applications can be significantly expanded. It can be used for nerve repair, wound auxiliaries, tissue engineering repair materials, drug slow-release and volume expansion, and even shows potential in fighting against COVID-19. Additionally, chitosan can enhance crop growth and be used as an antioxidant coating in agriculture.
Chitosan is a biodegradable natural polymer derived from the exoskeleton of crustaceans. Because of its biocompatibility and non-biotoxicity, chitosan is widely used in the fields of medicine and agriculture. With the latest technology and technological progress, different active functional groups can be connected by modification, surface modification, or other configurations with various physical, chemical, and biological properties. These changes can significantly expand the application range and efficacy of chitosan polymers. This paper reviews the different uses of chitosan, such as catheter bridging to repair nerve broken ends, making wound auxiliaries, as tissue engineering repair materials for bone or cartilage, or as carriers for a variety of drugs to expand the volume or slow-release and even show potential in the fight against COVID-19. In addition, it is also discussed that chitosan in agriculture can improve the growth of crops and can be used as an antioxidant coating because its natural antibacterial properties are used alone or in conjunction with a variety of endophytic bacteria and metal ions. Generally speaking, chitosan is a kind of polymer material with excellent development prospects in medicine and agriculture.
