NMR Relaxation of Mn0.5Zn0.5GdxFe(2-x)O4 Hyperthermia Nanoparticles: Effects of Coating
Introduction: Recent technical advances have made available magnetic nanoparticles (MNPs) of different compositions, coating, sizes, and size distributions leading to different chemical and physical properties and a range of applications (e.g. molecular imaging). We studied the 1/T1 and 1/T2 behaviour with MNP concentration and also explored the effect of the coating for a new class of MNPs com...

متن کاملEffect of coating thickness of iron oxide nanoparticles on their relaxivity in the MRI
Objective(s):Iron oxide nanoparticles have found prevalent applications in various fields including drug delivery, cell separation and as contrast agents. Super paramagnetic iron oxide (SPIO) nanoparticles allow researchers and clinicians to enhance the tissue contrast of an area of interest by increasing the relaxation rate of water. In this study, we evaluate the dependency of hydrodynamic si...

متن کاملHighly controlled silica coating of PEG-capped metal nanoparticles and preparation of SERS-encoded particles.
Thiol-modified poly(ethylene glycol) (mPEG-SH) has been used to replace standard capping agents from the surfaces of gold nanoparticles with different sizes and shapes. Upon PEG stabilization, the nanoparticles can be transferred into ethanol, where silica can be directly grown on the particle surfaces through the standard Stober process. The obtained silica shells are uniform and homogeneous, ...
