Uniform 3 nm-sized ceria nanoparticles can protect against ischemic stroke by scavenging reactive oxygen species (ROS) and reducing apoptosis. PEGylated ceria nanoparticles showed protective effects against ROS-induced cell death in vitro. Optimal doses of ceria nanoparticles reduced infarct volumes and the rate of ischemic cell death in vivo.

Nanoparticles are widely used in different applications such as cancer cell treatment and antibacterial agents. SnO2 nanoparticles were synthesized successfully by hydrothermal method and subsequent calcination using Tin (II) chloride- dihydrate, Sodium hydroxide, in presence of Hexadecyltrimethylammoniumn bromide (CTAB) as Surfactant. These nanoparticles were characterized by using Fourier tra...

BACKGROUND The sentinel lymph node biopsy (SLNB) was developed as a new modality in the surgical diagnosis of lymph node metastases. Dye and radioisotope are major tracers for the detection of sentinel lymph nodes (SLN). Dye tends to excessively infiltrate into the interstitium due to their small size (less than several nanometers), resulting in difficulties in maintaining clear surgical fields...

Iron oxide nanoparticles made from the thermal decomposition method are highly uniform in all respects (size, shape, composition and crystallography), making them ideal candidates for many bioapplications. The surfactant coating on the as-synthesized nanoparticles renders the nanoparticles insoluble in aqueous solutions. For biological applications nanoparticles must be water soluble. Here we d...

Finely dispersed sandwich composite nanoparticles of Cu–Ni–Cu were prepared by a novel method combining template synthesis and an ultrasonic treatment method. The composite nanoparticles have uniform cylinder shape with tunable diameter and length. Transmission electron microscopy (TEM) and electron diffraction (ED) were employed to characterize the nanoparticles. This method can be used to fab...

Magnetic nanoparticles are promising molecular imaging agents due to their relatively high relaxivity and the potential to modify surface functionality to tailor biodistribution. In this work we describe the synthesis of magnetic nanoparticles using organic solvents with organometallic precursors. This method results in nanoparticles that are highly crystalline and have uniform size and shape. ...

We report a new one phase method for the synthesis of uniform monodisperse crystalline Ag nanoparticles in aqueous systems that has been developed by using newly synthesized mono and dihydroxylated ionic liquids and cationic surfactants based on 1,3-disubstituted imidazolium cations and halogens anions. The hydroxyl functionalized ionic liquids (HFILs) and hydroxyl functionalized cationic surfa...

Block copolymer micellar templates were used for the controlled synthesis of large arrays of mono-metallic (Fe, Co, Ni, Mo) and bi-metallic (Fe–Mo) nanoparticles with average diameters ranging from 1 to 4 nm and the distance between the nanoparticles ranging from 40 to 45 nm. XPS data reveal the presence of mono-metallic nanoparticles in their oxidized states. These uniform arrays of nanopartic...

in the present work, the synthesis of barium hexaferrite (bafe12o19) nanoparticles in thepresence of a large excess amount of oh− anions by the hydrothermal method in the presence and absence of surfactants such as sodium dodecyl benzene sulfonate and triton x-114 was reported. the optimized temperature in the absence of surfactant was determined (200 °c) and then barium hexaferrite nanoparticl...
