In today’s continuous development of numerous fields such as materials science and biomedicine, chitosan, as a unique natural biomaterial, is showing extremely broad application prospects with its excellent properties and diverse functions. Chitosan, a polysaccharide substance extracted from the shells of crustaceans such as shrimps and crabs, has a variety of unique chemical and physical properties, thus laying a solid foundation for its application in multiple fields. I. Unlimited Potential in the Healthcare Field In the healthcare field, the application prospects of chitosan are highly noticeable. It has excellent biocompatibility and biodegradability, which makes it an ideal medical material. 1. New Hope for Wound Care – In terms of wound healing, chitosan shows unique advantages. It can form a micro – environment conducive to cell migration and proliferation, accelerating the wound – healing process. Moreover, chitosan has certain antibacterial activity and can inhibit the growth of common bacteria at the wound, such as Staphylococcus aureus and Escherichia coli. Currently, some advanced chitosan wound dressings have entered the clinical trial stage and are expected to bring better treatment effects to patients with chronic wounds, burns, etc. 2. Innovation in Drug Delivery Systems – Chitosan also has great potential in the field of drug delivery. It can be made into nanoparticles or microspheres to encapsulate various drug molecules. These chitosan carriers can protect drugs from degradation by enzymes in the body and can achieve controlled release of drugs in specific physiological environments. This is of great significance for fields that require precise drug delivery, such as cancer treatment and cardiovascular disease treatment. For example, in the delivery of anti – cancer drugs, chitosan nanoparticle carriers can accurately transport drugs to tumor tissues, increasing the drug concentration at the tumor site while reducing side effects on normal tissues. II. A Rising Star in the Food Industry 1. Food Preservation and Packaging – In the food industry, chitosan is emerging. Due to its antibacterial properties and the ability to form edible films, it can be used for food preservation and packaging. Chitosan films can effectively prevent the invasion of oxygen, moisture, and microorganisms, prolonging the shelf life of food. For example, for fresh fruits and meat products, the use of chitosan packaging can reduce the risk of spoilage and deterioration and reduce food loss. 2. Functional Food Additives – Chitosan can also be used as a functional food additive. It has the functions of regulating blood lipids and reducing cholesterol and is expected to be developed into a new type of healthy food ingredient. Some studies have shown that chitosan can bind to fats and cholesterol in the intestine, preventing them from being absorbed by the human body, thus playing an active role in protecting cardiovascular health. III. A Capable Assistant in the Environmental Protection Field 1. Wastewater Treatment – In terms of environmental protection, chitosan shows extraordinary capabilities in wastewater treatment. It can adsorb heavy metal ions such as lead, mercury, and cadmium in wastewater and can also remove organic pollutants in wastewater. The adsorption principle is based on the interaction between functional groups such as amino and hydroxyl groups on the chitosan molecule and pollutants. With the increasingly strict environmental protection requirements, the application of chitosan in industrial wastewater treatment is expected to be further promoted. 2. Soil Improvement – Chitosan also has a positive improvement effect on soil. It can improve the water – and – fertilizer – retaining capacity of the soil, promote the activity of soil microorganisms, and improve the soil structure. In some contaminated soil remediation, chitosan can combine with harmful substances in the soil, reducing their bio – availability, thereby restoring the soil to a healthy state. Although the application prospects of chitosan are very broad, it still faces some challenges at present. For example, the extraction cost of chitosan is relatively high, and the process of its large – scale industrial production needs further optimization. In addition, in some applications, the performance stability of chitosan needs to be further improved. However, with the continuous development of science and technology and in – depth research, many scientific research institutions and enterprises are actively exploring the potential of chitosan. An expert said: “We believe that in the next few years, with technological breakthroughs, chitosan will be applied on a large scale in more fields, bringing huge changes to human health, food, environment, etc.” Chitosan, with its unique advantages in healthcare, food industry, environmental protection and other fields, is undoubtedly a natural biomaterial with great development potential, and its application prospects are full of infinite possibilities.
