Photoswitchable Fluorescent Silica Nanoparticles and Method for Preparing the Same

摘要

The present invention provides a photochromic material and a fluorescent material is directed to a bonded to the surface of silica particles of silica nanoparticles and a method of manufacturing the same, more specifically, the photochromic with the ionic functional groups exposed silica nanoparticles surface this property is combined with phosphor materials relates to high absorbance, silica nanoparticles and a production method having a high sensitivity of the fluorescence and fluorescence jeonhwanseong. ; The present invention is high photochromic material and the fluorescent material is bonded silica nanoparticles detected sensitivity due to the excellent photoelectric bicyclic may be useful as an imaging contrast agent in vivo. ; photoelectric shout, photo chromism, silica, fluorescent nanoparticles, optical, high-sensitivity
