High density chitosan is widely used in the biomedical field for wound healing and tissue engineering due to its biocompatibility and biodegradability. It serves as an effective material for creating scaffolds that support cell growth and regeneration. In the pharmaceutical industry, it is utilized as a drug delivery vehicle, enabling controlled release of medications. Its antimicrobial properties make it valuable in developing coatings for medical devices to prevent infections. In the food industry, it acts as a thickener, stabilizer, and preservative to extend shelf life and improve texture. Additionally, it is employed in water treatment processes for its ability to bind and remove heavy metals and other contaminants. In agriculture, it acts as a natural biopesticide and seed coating agent to enhance plant growth and resistance to diseases. In cosmetics, it is used in skincare products for moisturizing, film-forming, and stimulating collagen production.
