Functionalization of iron oxide nanoparticles with biosurfactants and biocompatibility studies.

J Sangeetha et al.

Journal of biomedical nanotechnology, 9(5), 751-764 (2013-06-28)

We present methodologies to functionalize iron oxide (Fe3O4) nanoparticles with biosurfactants and biocompatibility results. Positively charged Fe3O4 nanoparticles of average hydrodynamic size -26 nm is functionalized with four different molecules of interest, viz., surfactin, rhamnolipid, polyethylene glycol (PEG) and dextran.

Dynamic investigation of interaction of biocompatible iron oxide nanoparticles with epithelial cells for biomedical applications.

Alice Panariti et al.

Journal of biomedical nanotechnology, 9(9), 1556-1569 (2013-08-29)

Magnetic nanoparticles have emerged as important players in current research in modern medicine since they can be used in medicine for diagnosis and/or therapeutic treatment of diseases. Among many therapeutic applications of iron-based nanoparticles, drug delivery and photothermal therapy are

Enhanced oxidation of nanoparticles through strain-mediated ionic transport.

Andrew Pratt et al.

Nature materials, 13(1), 26-30 (2013-11-05)

Geometry and confinement effects at the nanoscale can result in substantial modifications to a material's properties with significant consequences in terms of chemical reactivity, biocompatibility and toxicity. Although benefiting applications across a diverse array of environmental and technological settings, the

Nanoscale Fe2O3-based catalysts for selective hydrogenation of nitroarenes to anilines.

Rajenahally V Jagadeesh et al.

Science (New York, N.Y.), 342(6162), 1073-1076 (2013-11-30)

Production of anilines--key intermediates for the fine chemical, agrochemical, and pharmaceutical industries--relies on precious metal catalysts that selectively hydrogenate aryl nitro groups in the presence of other easily reducible functionalities. Herein, we report convenient and stable iron oxide (Fe2O3)-based catalysts

Comparison of contrast agents for atherosclerosis imaging using cultured macrophages: FDG versus ultrasmall superparamagnetic iron oxide.

Tomoko Satomi et al.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 54(6), 999-1004 (2013-05-15)

Various noninvasive imaging methods have been developed to evaluate atherosclerotic plaques. Among them, (18)F-FDG PET and MR imaging with ultrasmall superparamagnetic iron oxide particles (USPIO) have been used to quantify plaque inflammation. Both methods are based on the efficient uptake
