Chitosan , medium molecular weight (300-1000 cP, 1 wt. % in 1% acetic acid at 25 °C) Mw ~ 1,250,000

Chitosan is widely utilized in research focused on various practical applications:

Biomedical Applications: Chitosan is used in drug delivery systems due to its biocompatibility and ability to encapsulate drugs, enhancing their stability and release profiles. For example, it can be formulated into nanoparticles for targeted cancer therapy.

Food Industry: As a natural preservative, chitosan extends the shelf life of food products by inhibiting microbial growth. Its application in food packaging films helps maintain freshness and safety.

Agriculture: Chitosan acts as a natural biopesticide and soil conditioner, promoting plant growth and resistance to diseases. It can be used to enhance crop yields while reducing the need for synthetic chemicals.

Water Treatment: This compound is effective in removing heavy metals and other contaminants from wastewater. Its ability to flocculate impurities makes it a valuable resource for environmental remediation.

Cosmetics: Chitosan is incorporated into skincare products for its moisturizing and wound-healing properties. It helps improve skin hydration and provides a protective barrier against environmental stressors.
