Nanofibers are a class of polymeric materials that has been highlight at the biomedical area because they exhibit high surface area and high porosity. Chitosan nanofibers have been widely used for biomedical applications due their biocompatibility, biodegradability and non-toxicity. Beyond these properties, chitosan has antimicrobial properties and healing properties that are interesting for use as support to skin repair like, for example, in burns. However, although the great potential of chitosan nanofibers for biomedical applications, they present unsatisfactory mechanical properties and low resistance to water. Then, this project aims at the production and characterization of chitosan nanofibers reinforced with cellulose nanocrystals in order to obtain appropriate biological and mechanical properties for application in tissue engineering.
