Mesoporous Silica Coated CeF3:Tb3+ Particles for Drug Release

Mesoporous Silica Coated CeF3:Tb3+ Particles for Drug Release

CeF3:Tb3+ nanoparticles were successfully prepared by a polyol process using diethylene glycol (DEG) as solvent. After being coated with dense silica, these CeF3:Tb3+ nanoparticles can be coated with mesoporous silica using nonionic triblock copolymer EO20PO70EO20 (P 123) as structure-directing agen...

The composite can load ibuprofen and release the drug in the PBS. The composite was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), nitrogen absorption/desorption isotherms, fluorescence spectra, and UV/Vis absorption spectra, respectively. The composite particles have considerable large pore volume and large surface area. In addition, the composite still emits strong green fluorescence (Tb3+) and can be used as fluorescent probes in drug delivery system.http://dx.doi.org/10.1155/2008/312792
