Drive-Field Frequency Dependent MPI Performance of Single-Core Magnetite Nanoparticle Tracers

Intracellular performance of tailored nanoparticle tracers in magnetic particle imaging.

Magnetic Particle Imaging (MPI) is a quantitative mass-sensitive, tracer-based imaging technique, with potential applications in various cellular imaging applications. The spatial resolution of MPI, in the first approximation, improves by decreasing the full width at half maximum (FWHM) of the field-derivative of the magnetization, dm/dH of the nanoparticle (NP) tracers. The FWHM of dm/dH depen...

Tracer design for magnetic particle imaging (invited).

Magnetic particle imaging (MPI) uses safe iron oxide nanoparticle tracers to offer fundamentally new capabilities for medical imaging, in applications as vascular imaging and ultra-sensitive cancer therapeutics. MPI is perhaps the first medical imaging platform to intrinsically exploit nanoscale material properties. MPI tracers contain magnetic nanoparticles whose tunable, size-dependent magnet...

Aggregation and sedimentation of magnetite nanoparticle clusters †

Magnetite nanoparticles are redox active constituents of subsurface and corrosive environments. In this study, we characterized the aggregation and sedimentation behavior of well characterized magnetite nanoparticle clusters using dynamic light scattering (DLS), UV-vis-NIR spectroscopy, and small angle X-ray scattering (SAXS). Both unfunctionalized (NaOH-magnetite) and tetramethylammonium hydro...

Magnetite Nanoparticle Green Synthesis from Canola Oil

Nanomagnetite can be synthesized in lab by decomposition method using FeOOH and oleic acid in 1-ODEbut the cost of production is very high. Here we are trying to synthesize cost effective nanomagnetites by using common materials present in our daily life which are freely available in market .Magnetite nanocrystals are highly useful in arsenic remediation as arsenic contamination in groundwater ...
