A facile fabrication of spherical and beanpod-like magnetic-fluorescent particles with targeting functionalities.

Magnetic-fluorescent particles with targeting functionalities were fabricated by a modified Stöber method and two shapes (spherical and beanpod-like) were obtained by simply tuning the reaction temperature. The two multifunctional probes combined the useful functions of magnetism, fluorescence and FA (folic acid)-targeting recognition into one entity. The products were characterized by scanning electron microscopy, transmission electron microscopy, photoluminescence spectroscopy, confocal laser scanning microscopy, by a superconducting quantum interference device and by Fourier transform infrared spectroscopy.

Synthesis and characterization of nano-PVP/EuL3 luminescent complex.

Nano-sized rare earth europium [Eu(III)]-benzoic acid [HL] luminescent complex powders have been synthesized in polyvinylpyrrolidone matrix by precipitation method. The chemical constitution of the complex has been demonstrated as PVP/EuL3 by a combination of elemental analysis, inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and fourier-transform infrared spectroscopy (FT-IR). X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM) have shown that the complex is a new nanocrystal whose structure is totally different from the ligand.

Synthesis and characterization of [Eu(DBM)3phen]Cl3 @ SiO2-NH2 composite nanoparticles.

Fluorescent rare earth complex Eu(DBM)3(phen)]Cl3@SiO2-NH2 nanoparticles were synthesized by combination of solvent precipitation method and Stöber method. The morphologies, structure, surface and optical properties of the samples were characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), fourier transform infrared (FTIR) spectroscopy, thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), and fluorescence spectrophotometer (FS). The observation from FE-SEM images indicate that the obtained samples are spherical and uniform nanoparticles with a tunable average sizes from 140 nm to 300 nm.

Metabolomic profiles delineate potential roles for gadolinium chloride in the proliferation or inhibition of Hela cells.

Lanthanides (Lns) compounds have been reported to possess contrary effects on cell activity, i.e., promoting cell cycle progression and cell growth by lower concentration treatment, but suppressing cell proliferation and inducing cell apoptosis at higher dosing.

Synthesis and characteristic of the Fe3O4@SiO2@Eu(DBM)3.2H2O/SiO2 luminomagnetic microspheres with core-shell structure.

The core-shell structured luminomagnetic microsphere composed of a Fe(3)O(4) magnetic core and a continuous SiO(2) nanoshell doped with Eu(DBM)(3).2H(2)O fluorescent molecules was fabricated by a modified Stöber method combined with a layer-by-layer assembly technique. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), confocal microscopy, photoluminescence (PL), and superconducting quantum interface device (SQUID) were employed to characterize the Fe(3)O(4)@SiO(2)@Eu(DBM)(3).
