Chitosan based bioadhesives for biomedical applications: A review

Due to the promising properties of chitosan for biomedical engineering applications like biodegradability, biocompatibility, and non-toxicity, it is one of the most interesting biopolymers in this field. Therefore, Chitosan and its derivatives have attracted great attention in vast variety of biomedical applications. In the current paper, different types of chitosan-based bioadhesives including passive and active and their different types of external stimuli response structure such as thermo, pH and Light responsive systems are discussed. Different bioadhesives mechanisms with chitosan as an adhesive agent or main polymer component and some examples were also presented. Chitosan based bioadhesives and their potential biomedical applications in drug delivery systems, suture less surgery, wound dressing and hemostatic are also discussed. The results confirmed wound healing, hemostatic and bioadhesion capabilities of the chitosan bioadhesives and its great potential for biomedical applications. [Display omitted]
