The cyanoethylchitosan was prepared to modify the glass carbon electrode through covalent-bond reaction.

FTIR spectroscopy was used to determine the degree of substitution (DS) of both acylated chitosans and cyanoethyl chitosans prepared from chitosan with the degree of deacetylation 84% and 70% respectively.

It is introduced that water-soluble O-hydroxyethyl chitosan (HECS) was synthesized and dissolved in NaOH solution to spin cellulose/HECS blend fiber by CC process,also the physical and antibacterial properties were examined.

In this paper,an efficient procedure to prepare N,O-carboxyethyl-chitosan(N,O-CE-CTS) was established by the reaction of 3-chloropropionic acid and chitosan.
