Application

Chitosan offers remarkable biological properties, it has been widely used in drug delivery and tissue engineering applications. Chitosan has good mucoadhesive properties due to its positive charge, which increases the adhesion to mucosa and facilitates drug penetration. Also, chitosan possesses hemostatic properties, which makes it a good candidate for wound dressing applications.

The quaternization of the primary amine increases the water solubility of chitosan and keeps chitosan soluble over a wide pH range. Among all the quaternized chitosans, N, N, N-trimethyl chitosan chloride (TMC) is the most widely applied in biomedical applications.

N-trimethyl chitosan chloride (TMC) is a polycation that enhances drug transport across epithelia by opening tight junctions. The degree of quaternization of TMC determines the number of positive charges available on the molecule for interactions with the negatively charged sites
