Magnetic γ-Fe(2)O(3) nanoparticles with a mean diameter of 20 nm and size distribution of 7% were chemically synthesized and spin-coated on top of a Si-substrate. As a result, the particles self-assembled into a monolayer with hexagonal close-packed order. Subsequently, the nanoparticle array was coated with a Co layer of 20 nm thickness. The magnetic properties of this composite nanoparticle/t...

Magnetic nanoparticles attract increasing attention because of their current and potential biomedical applications, such as, magnetically targeted and controlled drug delivery, magnetic hyperthermia and magnetic extraction. Increased magnetization can lead to improved performance in targeting and retention in drug delivery and a higher efficiency in biomaterials extraction. We reported an appro...

Temporally, spatially, and thermally resolved measurements of in situ nanoparticle cloud formation during combustion single micron-sized iron particles are carried out. The critical particle temperature for the is identified using high-speed high-magnification shadowgraphy, recording evolution a cloud, synchronized with two-color pyrometry probing surface burning micron particle. finding could ...

Intravenous iron therapy is pivotal in the treatment of anemia of chronic kidney disease to optimize the response of hemoglobin to erythropoiesis-stimulating agents. Intravenous iron use in patients with chronic kidney disease is on the rise. Recent clinical trial data prompting safety concerns regarding the use of erythropoiesis-stimulating agents has stimulated new US Food and Drug Administra...

In this work, preparation and crystallization of yttrium iron garnet Y3Fe5O12 super-paramagnetic nanoparticle by aqueous sol–gel processes and its application as an effective nano catalyst for esterification and etherification reactions in short reaction time and in high isolated yields. Then this catalist was used for the synthesis of Dihydropyrimidin derivatives is described. The catalyst was...

Abstract The aim of this study was to develop a novel multifunctional nanoparticle, which encapsulates SPION and Gemcitabine in PLGA±PEG to form multifunctional drug delivery system. For this aim, super paramagnetic iron oxide nanoparticles (SPIONs) were synthesized and encapsulated simultaneously with Gemcitabine (Gem) in PLGA±PEG copolymers via W/O/W double emulsification me...

Site-selective growth of multi-walled carbon nanotubes (MWCNTs) from an iron oxide nanoparticle catalyst patterned by drying-mediated self-assembly technique is present. The ethanol solution of the iron nitrate was employed as catalyst precursor. The catalyst precursor was mounted on silicon wafer by dip-coating. After evaporation of solvent at room temperature, the catalyst pattern formed. The...

The decomposition of organometallic compounds as precursors has revolutionized the synthesis of nanoparticles in solution. However, effective control of size and size distribution of iron nanoparticles has remained challenging due to the high reactivity of iron towards oxygen or oxygen-containing materials. Reported is a decomposition study that shows how metal to ligand bonding and symmetry of...

Conjugation of monoclonal antibodies to super paramagnetic nanoparticles is an effective method for cancer diagnosis and treatment. In this study the humanized anti her2/neu monoclonal antibody- Herceptin- was conjugated to super paramagnetic iron oxide (SPIO) nanoparticles using EDC method. The concentration of the conjugated antibodies was measured by Bradford assay. The antibody-nanoparticle...
