Abstract:
PURPOSE: A gene delivery system for transferring a target gene to cells is provided to enable stable delivery of the gene delivery system to an organism and to effectively suppress the expression of a specific disease gene. CONSTITUTION: A gene delivery system for transferring a target gene to cells is complexed by ionic interaction through mixing the target gene with polyethylene imine of Branched polyethylenimine cross-linked via disulfide bonds(ssPEI). The target gene is siRNA(small interfering RNA), an antisense molecule, an antagonist, ribozyme, an inhibitor, a peptide, or a small molecule. The target gene is siRNA which is specific to Akt gene. The target gene is fixed on a support. The support is a stent coated with hyaluronic acid or collagen on the surface.
Abstract:
PURPOSE: An intracellular gene delivery intracellular gene delivery containing cationic polymers and magnetic nanoaprticels is provided to treat various diseases using a gene. CONSTITUTION: An intracellular gene delivery composite contains cationic polymers of 1000-10,000 Da of molecular weight and magnetic nanoparticles. The cationic polymers are polyethylene imine(PEI), poly-L-lysine(PLL), or chitosan. The magnetic nanoparticles are thermally cross-linked superparamagnetic nanoparticles(TCL-SPION). The intracellular gene delivery composite is prepared by cross-linking of the cationic polymers and magnetic nanoparticles under the presence of -ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride(EDC) and N-hydroxysuccineimide(NHS).
Abstract:
A mannan-coated superparamagnetic iron oxide nanoparticle is provided, which enables specific flow of liver to kupffer cell and ensure stability of ferrofluid. A contrast media for diagnosing hepatism comprises a mannan coated superparamagnetic iron oxide nanoparticle. A method for manufacturing the nanoparticle comprises: a step of adding basic solution in iron chloride aqueous solution and dipping iron oxide nanoparticle; a step of oxidizing the iron oxide nanoparticle and producing storage solution; and a step of mixing mannan solution in the storage solution, stirring and coating.
