Abstract: Disclosed is a polymer-siRNA delivery carrier in which a siRNA is combined with a polymer and the use thereof. More specifically, there is disclosed a stable in vivo polymer-siRNA delivery carrier in which a polymer and a siRNA are combined by using charge interaction and biodegradable covalent bonding at the same time and the use thereof. The polymer-siRNA delivery carrier in which a polymer and a siRNA are combined by using charge interaction and biodegradable covalent bonding at the same time has a high siRNA deliver efficiency to a target portion in vivo. Hence, according to the polymer-siRNA binder, the siRNA for treatment can be effectively delivered to a target portion such as in vivo cancer tissue, and the like even with administration of a relatively low concentration, and thus widely used for the treatment of various kinds of diseases.

Abstract: The oligonucleotide polymerization method of the present invention is advantageous in that an oligonucleotide with a small molecular weight can be easily polymerized into high-molecular weight oligonucleotides. Further, the high-molecular oligonucleotide prepared by the method of the present invention can bind to hydrophilic high-molecular materials or inorganic materials, and then can be stably delivered to a living body. Therefore, the high-molecular oligonucleotide prepared by the method of the present invention can be widely used for treating various diseases.

Abstract: Disclosed are a human serum albumin-siRNA carrier system having siRNA bound to human serum albumin and a user thereof, and especially, human serum albumin-siRNA carrier system, which has a biodegradable covalent bond between human serum albumin polymer and siRNA and is stable in a living body, and a user thereof. The human serum albumin-siRNA carrier system having the biodegradable covalent bond between the human serum albumin and the siRNA exhibits high siRNA delivery efficiency to a target site in the living body. Therefore, the human serum albumin-siRNA carrier system may allow siRNA for therapy to be efficiently delivered to a target site such as cancer tissues in the living body even by being administrated in a relatively low concentration, which may result in a wide use for therapies of various diseases.
