Title:
COMPOSITION FOR GENE DELIVERY COMPRISING CHITOSAN AND LIQUID CRYSTAL FORMATION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2014/133351
Kind Code:
A1
Abstract:
Disclosed herein is a composition for gene delivery which forms into liquid crystals in an aqueous fluid including chitosan and a liquid crystal formation material. The composition of the present invention including chitosan and a liquid crystal formation material improves the relatively low binding strength between chitosan and a gene, and also considerably increases the stability of a chitosan nanocomposite in blood serum, thereby performing highly efficient gene delivery and providing excellent stability, thus being useful as a gene therapeutic agent.
