Optimization of synthesis conditions to prepare desired shell thickness of superparamagnetic MgFe2O4@SiO2 core-shell nanosphere for biomedical applications

, , , , , , , ,
We have described here a simple way for the fabrication of superparamagnetic MgFe2O4@SiO2 core-shell spherical nanoparticles with controlled shell thickness. First, core MgFe2O4 dense nano-spheres were directly synthesized by ultrasonic spray pyrolysis (USP) technique from [...]

Green, Cubic Y2O3: Tb3+ Nanospheres: Synthesis and Photoluminescence Property

, , , , , , , , , , ,
Tb3+-doped Y2O3 green nanospheres were prepared via the simple, cost-effective urea homogeneous precipitation method without additives. Nanospheres were characterized by X-ray diffraction, Scanning electron microscope, Photoluminescence spectroscopy. The specimens annealed above 800oC are well matched [...]

Development of Nanoparticle-Based Gold Contrast Agent for Photoacoustic Tomography

, , , , , ,
Photoacoustic tomography (PAT) utilizes non-ionizing energy to obtain structural/functional information with high spatial resolution and sensitivity. Heterogeneous absorption of optical energy in biological tissues results in differentially expressed acoustic signals yielding spatial/temporal information. A critically [...]
