in this study, we synthesized herceptin conjugated magnetic nanoparticles (hmns) as an alternative probe to discover the levels of her2 (human epidermal growth factor receptor-2) in the surface of cells. these nanoparticles can be used by magnetic resonance imaging (mri) (non-invasive methods) for screening the patients with her2 positive or negative tumors. dextran coated iron oxide nanopartic...

results the maximum si was obtained at the highest applied flip angle (45°). the linear relationship between si and nanoparticle concentration was seen up to 112.21 and 98.83 μmol fe/l for the short (10°) and the long (45°) flip angles, respectively (r2 = 0.95). these values were reduced up to 48.54 and 42.73 μmol fe/l for these flip angles with r2 of 0.99. conclusions the maximum si will be in...

To utilize iron oxide nanoparticles in biomedical applications, a sufficient magnetic moment is crucial. Since this magnetic moment is directly proportional to the size of the superparamagnetic nanoparticles, synthesis methods of superparamagnetic iron oxide nanoparticles with tunable size are desirable. However, most existing protocols are plagued by several drawbacks. Presented here is a one-...
