Description

Chitosan is widely utilized in biomedical applications. It finds applications in plantations as natural seed treatment and a growth enhancer. It serves as a fining agent in winemaking and also prevents spoilage. It is involved in the field of medicine to reduce bleeding and as an antibacterial agent. It is used in self-healing coatings which are applied in industrial applications. It is also employed as a part of a filtration process to remove phosphorus, heavy minerals and oils from water.
