Abstract

Disclosed are a metal-nanoparticle-based liver-specific nucleic acid delivery system, a method of manufacturing the same, and a liver disease treatment composition containing the same. The liver-specific nucleic acid delivery system is coated with a bile acid-glycol chitosan polymer, so that it provides excellent liver-tissue specificity and high absorbance through digestive canals. Since the nucleic acid of the nucleic acid delivery system is coated with the bile acid-glycol chitosan polymer, it can be protected from decomposition of enzymes and the like inside a living organism. The liver-specific nucleic acid delivery system can be developed as an oral-administrating liver-disease treatment.
