Chitosan is partially or completely N-deacetylated derivative of chitin and is chemically composed of β-(1, 4) linked 2-amino-2-deoxy-β-d-glucopyranose. It is a natural polymer polysaccharide derived from marine crustaceans. Unlike chitin, chitosan is readily soluble in weak acid solutions. In addition, the chemical and biochemical reactivity of chitosan is higher than that of chitin because chitosan has free primary amino groups regularly distributed along its molecular chain. As one of the most abundant natural biopolymers, chitosan has a wide range of applications due to its versatile biological activity, good biocompatibility, complete biodegradability and low toxicity.

In agriculture, chitosan induces host defense responses in monocotyledons and dicotyledons. It has been described as a plant antiviral agent and as an additive in liquid multi-component fertilizers. In addition, the presence of chitosan on the soil facilitates symbiotic interactions between plants and microorganisms. Chitosan can also improve plant metabolism, resulting in increased germination rates and crop yields.
Due to its immunostimulatory activities, anticoagulant properties, antibacterial and antifungal effects and its role as a wound healing promoter in the field of surgery, chitosan can be used extensively as a biomedical material. In addition, chitosan can also be used as a potential excipient in the form of granules or beads for the sustained release of orally administered drugs. This is mainly due to its abundant availability, inherent pharmacological properties and low toxicity.
Chitosan is biocompatible and is compatible with other ingredients such as glucose, oils, fats and acids. It is a highly effective hydrating agent with film-forming ability. Chitosan is commonly used in skin care applications. It helps to retain skin moisture, moisturize and firm the skin, provide extracellular matrix support and promote the skin's natural barrier function.
Chitosan can be used as an excellent coagulating agent and flocculant in wastewater treatment, protein recovery and water purification. This is mainly due to the high density of amino groups in the polymer chains, which can interact with negatively charged substances such as proteins, solids and dyes.
In addition to the applications in the above fields, chitosan can also be used as a dye binder for textiles, a strengthening additive in paper, and a preservative in foods, etc.
