in this study we report the rock magnetic properties of surface soil samples and their spatialvariability from the northernmost district of kerala to understand pedogenic processes and soil erosion. themagnetic signal is mainly from fine grained pedogenic magnetite as other sources like anthropogenic andlithogenic magnetite, bacterial magnetite and greigite are absent. the surface soil samples ...

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...

in this paper the role of super paramagnetic iron oxide nanoparticles (spi) on platinum nanoclusters on activated carbon (pt/c) for electrocatalytic oxygen reduction reaction was considered. four composites of pt/c and super paramagnetic iron oxide nanoparticles were prepared with the same total composites weight and different loading of pt/c (1.2, 0.6, 0.4 and 0.3 mg ). the composite attached ...

A novel nanofibrous composite scaffold composed of super-paramagnetic γ-Fe2O3 nanoparticles (MNP), hydroxyapatite nanoparticles (nHA) and poly lactide acid (PLA) was prepared using electrospinning technique. The scaffold well responds extern static magnetic field with typical saturation magnetization value of 0.049 emu/g as well as possesses nanofibrous architecture. The scaffolds were implante...

objective(s): this study describes the preparation, biodistribution of 153sm-dtpa-spion after intravenous injection in rats. materials and methods: the chelator dtpa dianhydride was conjugated to spion using a small modification of the well-known cyclic anhydride method. conjugation was done at a 1: 4 (spion: ccdtpa) molar ratio. conjugation reaction was purified with magnetic assorting column ...

A rapid and sensitive chemiluminescence microfluidic immunoassay system based on super-paramagnetic microbeads for determination of alpha-fetoprotein (AFP) is described. In this system we use CO(2) laser to fabricate microfluidic chip, and use super-paramagnetic microbeads as solid carrier of antibody, chemiluminescence as detection signal. With this system we can perform AFP analysis within 20...

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 method. optimum size and enca...
