Sterilization of chitosan: implications.

Chitosan, a biopolysaccharide having structural characteristics similar to glycosaminoglycans, seems to be an ideal non-toxic and bioabsorbable biopolymer. This study highlights the effects of some physical and chemical methods of sterilization on chitosan films, in retaining the original tensile strength besides the efficacy of sterility and degree of hemolysis of the finished films.
