Abstract:
The present invention relates to a composition for visualizing atherosclerosis and a diagnosis method of atherosclerosis using the same. According to the present invention, the composition for visualizing atherosclerosis has excellent accuracy for diagnosing atherosclerosis, and can diagnose atherosclerosis of a disease carrier who needs regulation of blood glucose such as diabetes, and can effectively diagnose atherosclerosis generated in the brain and heart. Also, the composition of the present invention can be produced at a low price compared with an existing visualization composition to diagnose atherosclerosis. Accordingly, the present invention can effectively diagnose atherosclerosis using the same.
Abstract:
PURPOSE: A nanoparticle containing a linker which is linked to a long alkane or alkene chain and a method for preparing the same are provided to easily introduce various ligands to the nanoparticles. CONSTITUTION: A nanoparticle containing a linker which is linked to a long alkane or alkene chain has an alkane or alkene part(R) of an alkane or alkene-introduced ligand(R-A-L) of chemical formula 1 coated on the surface of hydrophobic nanoparticles by non-covalent bond. A method for preparing the same comprises: a step of removing organic solvent from the hydrophobic nanoparticles dissolved in the organic solvent or mixing the hydrophobic nanoparticles with the compound of chemical formula 1, PEG derivatives, and a solution containing detergent; and a step of dissolving the mixture.
