Evaluation of iron oxide nanoparticle biocompatibility
Nanotechnology is an exciting field of investigation for the development of new treatments for many human diseases. However, it is necessary to assess the biocompatibility of nanoparticles in vitro and in vivo before considering clinical applications. Our characterization of polyol-produced maghemite γ-Fe(2)O(3) nanoparticles showed high structural quality. The particles showed a homogeneous sp...
متن کاملPolyvalent oligonucleotide iron oxide nanoparticle "click" conjugates.
We have utilized the copper-catalyzed azide-alkyne reaction to form a dense monolayer of oligonucleotides on a superparamagnetic nanoparticle core. These particles exhibit the canonical properties of materials densely functionalized with DNA, which can be controlled by modulating the density of oligonucleotides on the surface of the particles. Furthermore, like their Au analogues, these particl...
متن کاملUHV-HREM and Diffraction of Surfaces
Characterization of the structure of surfaces is very important in order to develop a fundamental understanding of the electronic, mechanical and chemical properties of a material. While transmission electron microscopy imaging (TEM) and diffraction (TED) techniques are capable of providing surface structural information at the atomic level, such data would be suspect if obtained under conventi...
متن کاملThe Effects of Iron Oxide Nanoparticle on Differentiation of Human Mesenchymal Stem Cells to Osteoblast
Introduction: IIron oxide nanoparticles (IO NP) have an increasing number of biomedical applications. To date, the potential cytotoxicity of these particles remains an issue of debate. Little is known about the cellular interaction or toxic effects of IO NP on differentiation of stem cells. The aim of the present study was to investigate the possible toxic role of different doses of IO NP in di...
متن کاملSuperparamagnetic iron oxide nanoparticle targeting of MSCs in vascular injury.
Vascular occlusion can result in fatal myocardial infarction, stroke or loss of limb in peripheral arterial disease. Interventional balloon angioplasty is a common first line procedure for vascular disease treatment, but long term success is limited by restenosis and neointimal hyperplasia. Cellular therapies have been proposed to mitigate these issues; however efficacy is low, in part due to p...
