The present invention relates to a fluorescent silica nanoparticle coated with a hydrophilic polymer and a method for preparing the same, and more particularly, to a fluorescent silica nanoparticle coated with a hydrophilic polymer such as dextran, a method for producing the same, and a biomolecule detection method using the same. The fluorescent silica nanoparticles coated with the hydrophilic polymer according to the present invention have improved dispersibility in an aqueous solution, and thus can maintain the improved dispersibility without addition of a hydrophilic polymer and a surfactant to the diagnostic solution during the molecular diagnosis, Antibody reaction, and the like. |
