The imine-bond formation on chitosan backbones occurs with very low yields in aqueous solutions and is significantly improved in hydrogels or in solid state films. The dynamic exchanges of imino-R groups and colour transfer can occur at the interfaces between various hydrogels and solid state films.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
