Magnetic interactions between nanoparticles
We present a short overview of the influence of inter-particle interactions on the properties of magnetic nanoparticles. Strong magnetic dipole interactions between ferromagnetic or ferrimagnetic particles, that would be superparamagnetic if isolated, can result in a collective state of nanoparticles. This collective state has many similarities to spin-glasses. In samples of aggregated magnetic...
متن کاملDesigning and Characterizing Hyperpolarizable Silicon Nanoparticles for Magnetic Resonance Imaging
Magnetic Resonance Imaging (MRI) is one of the most powerful noninvasive tools for diagnosing human disease, but its utility is limited because current contrast agents are ineffective when imaging air-tissue interfaces, in regions with low signal-to-noise ratios, or in areas that undergo motion, like the heart and bowel. A technique called dynamic nuclear polarization can be used to hyperpolari...
متن کاملMultifunctional silica nanoparticles for optical and magnetic resonance imaging.
The surface of spherical, nonporous silica nanoparticles (SiO2-NPs) was modified with gadolinium (Gd) complexes, fluorophores, and cell-penetrating peptides to achieve multifunctionality on a single particle. The Gd surface concentrations were 9-16 μmol/g resulting in nanomaterials with high local longitudinal and transversal relaxivities (~1×10(5) and ~5×10(5) /mm/s/NP, respectively). Rapid ce...
متن کاملGadolinium loaded nanoparticles in theranostic magnetic resonance imaging.
Theranostic magnetic resonance imaging (MRI) is now receiving a growing interest in imaging-guided drug delivery, monitoring the treatment and personalized administration etc. Theranostic agents are essential for the usage of theranostic MRI. Among different kinds of theranostic agents, gadolinium loaded nanoparticles (GdNPs) are one of the most promising theranostic agents which are very promi...
