Chitosan is widely used in the field of biomedicine due to its biocompatibility and biodegradability. It is employed in wound healing products, such as dressings and gels, to promote tissue regeneration and reduce infection risks. In drug delivery systems, chitosan acts as a carrier for controlled release of medications, enhancing their efficacy and stability.

In agriculture, chitosan is applied as a natural biopesticide and plant growth enhancer, improving crop resistance to diseases and increasing yields. It is also used in water treatment processes to remove heavy metals and other contaminants due to its chelating properties.

In the food industry, chitosan serves as a preservative and edible coating to extend the shelf life of perishable products. Additionally, it is utilized in weight loss supplements for its ability to bind dietary fats and reduce their absorption in the digestive system.

In cosmetics, chitosan is incorporated into skincare products for its moisturizing and antimicrobial properties, helping to improve skin health and appearance. Its versatility makes it a valuable material across various industries.
