title: Different Chitosan-Based Biomaterials and their Biomedical Applications
abstract: Chitin, the second most available marine biopolymer, was firstly used in the 1930s and early 1940s. Chitosan, derived from chitin, is a natural polymer that is known for being biodegradable, non-toxic and antibacterial It is cationic, has a hydrophilic surface and causes minimal foreign-body reaction Also, chitosan shows a reasonable solubility in water and in organic acids. However, this represents the major limitation to chitosan's preparation and use for biomedical applications. Also, shows a
