Chitosan, a low molecular weight biopolymer derived from chitin, is recognized for its versatile applications across various industries. With a molecular weight ranging from 50,000 to 190,000 Da, Chitosan exhibits excellent solubility in acidic environments, making it particularly useful in pharmaceuticals, agriculture, and food technology. Its natural biocompatibility and biodegradability position it as a preferred choice for drug delivery systems, wound dressings, and as a food preservative. Researchers have leveraged Chitosan's antimicrobial properties to develop effective coatings that enhance the shelf life of perishable goods while maintaining food safety.

In addition to its applications in health and food industries, Chitosan is also utilized in water treatment processes due to its ability to flocculate and remove contaminants. Its unique characteristics, such as non-toxicity and the ability to form gels, allow for innovative uses in tissue engineering and regenerative medicine. As a natural polymer, Chitosan stands out for its sustainability and eco-friendliness, making it an attractive option for environmentally conscious applications.
