Abstract: The present invention is directed to a glycol chitosan derivative having a hydrophobic substituent, to a method for preparing the glycol chitosan derivative, and to a use of the glycol chitosan derivative. In particular, the glycol chitosan derivative has a structure where an amine group at the 2-position is partially substituted with an acetyl group and a hydrophobic group R and is utilized in medical, bio, electric and other fields, by virtue of its thermo-sensitive characteristics of causing sol-gel transition at a predetermined temperature.

Abstract: The present invention relates to a glycol chitosane derivative, a preparation method thereof and a drug delivery system comprising the same. More specifically, the invention relates to a glycol chitosan derivative, which can form nano-sized self-assembled structures and has both temperature sensitivity and biodegradability so as to be suitable for use as a drug delivery system, as well as a preparation method thereof and a drug delivery system comprising the same.
