RF rotating plasma modified of chitosan with 3,4-ethylenedioxythiophene, thiophene and furan: Investigation of nanofibers in-situ with quartz crystal microbalance (QCM) and electrospinning system

Chitosan is a biocompatible aminopolysaccharide, N-deacetylated biopolymer of chitin that is the second abundant natural polymers on the earth^1,2. Because of its favorable physicochemical and biological properties such as its being biocompatible, low toxicity, ecological safety and biodegradable, chitosan is considered as an attractive material that can potentially be used in the biomedical and pharmaceutical fields^3-7. Nevertheless, recent researches have been focused on modification of the surface of chitosan using the different methods⁷.
