Chitosan, a linear polysaccharide, is a fascinating biopolymer with a unique structure that underpins its remarkable versatility. Derived from chitin, which is abundant in the exoskeletons of crustaceans and fungi, chitosan consists of randomly distributed beta-(1→4)-linked D-glucosamine and N-acetyl-D-glucosamine units. The degree of deacetylation (DDA), which refers to the percentage of deacetylated units, is a critical factor influencing its physicochemical properties and, consequently, its applications.

The production of chitosan typically involves the alkaline deacetylation of chitin. The resulting properties, such as solubility, viscosity, and biological activity, are highly dependent on the DDA and molecular weight. For instance, higher DDAs generally correlate with improved solubility in acidic solutions and enhanced antimicrobial efficacy, crucial for applications like chitosan for food preservation and as a biopesticide in agriculture. NINGBO INNO PHARMCHEM CO.,LTD. meticulously controls these parameters during production to ensure optimal quality for various industrial needs.

The scientific understanding of chitosan's functionality is key to its diverse applications. In water treatment, its positively charged amino groups effectively bind to negatively charged heavy metal ions and pollutants, making it valuable for chitosan for wastewater treatment. In biomedicine, its biocompatibility and ability to promote cell adhesion and growth are harnessed for wound healing and tissue engineering, as seen in chitosan for wound management applications. Its film-forming capabilities are also exploited in biodegradable packaging and as carriers for controlled release of active ingredients in drug delivery, highlighting the importance of chitosan nanoparticle drug delivery research.
