Fluorescent mesoporous silica nanoparticles functionalized with carboxyl group (Znq-CMS-COOH) were successfully synthesized by in situ formation route of 8-hydroxyquinolinate zinc complexes in channels of mesoporous silica nanoparticles and post-grafting of carboxyl group on the surface.Moreover,the particle size and structural properties of Znq-CMS-COOH were characterized by transmission electron microscopy (TEM),field emission scanning electron microscopy (FE-SEM),dynamic light scattering (DLS),Fourier transform infrared spectroscopy (FT-IR),UV-vis spectrometer,fluorescence spectrometer and nitrogen adsorption-desorption measurements.The obtained results suggest that the Znq-CMS-COOH presents the uniform spherical shape with the mean diameter of about 85 am and the obvious wormhole arrangement mesoporous.In addition,the Znq-CMS-COOH possesses green fluorescence with the emission peaks at 495 nm.So the Znq-CMS-COOH,which is beneficial to further modification and tracing,might be a great potential carrier for applying in drug delivery system in the future.
