Research on development and fabrication of polymer based artificial skin and implants for tissue engineering applications is focused using advanced materials and fabrication technology. Chitin or chitosan can be used to prepare biocompatible materials for artificial skin, or organs. Eelectrospun chitin nanofibers can be used as reinforcement of high performance non-toxic fibrous scaffolds. Such scaffold could be an alternate to native skin regarding substantial unique properties. 3-D bioprinted chitin can also be used for highly specific and sensitive smart skin.
