Multifunctional nanoparticle-mediated imaging and therapeutic techniques are promising modalities for accurate localization and targeted treatment of cancer in clinical settings. Thermoacoustic (TA) imaging is highly sensitive to detect the distribution of water, ions or specific nanoprobes and provides excellent resolution, good contrast and superior tissue penetrability. TA therapy is a poten...

background susceptibility-weighted imaging (swi) is extremely sensitive in the detection of superparamagnetic iron oxide (spio) nanoparticle-labeled cells. however, no study has compared molecular imaging for stem cell detection using swi and other mri pulse sequences. objectives this study aims to assess the sensitivity of swi in detecting spio nanoparticle-labeled, human bone marrow-derived m...

In the present work, hematite (α-Fe2O3) nanoparticles (NPs) were synthesized by using a simple and facile green synthesis Hibiscus plant extract. The used solution is composed of extract 0.1 M iron chloride mixture. are grown at ambient temperature. prepared morphology, structure composition characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscop...

OBJECTIVE The objective of this study was to evaluate the effect of the labeling of umbilical cord vein derived mesenchymal stem cells with superparamagnetic iron oxide nanoparticles coated with dextran and complexed to a non-viral transfector agent transfector poly-L-lysine. METHODS The labeling of mesenchymal stem cells was performed using the superparamagnetic iron oxide nanoparticles/dext...

The magnetic properties of Fe$_3$O$_4$ nanoparticle assemblies have been investigated in detail through a combination vibrating sample magnetometry and muon spin relaxation ($\mu$SR) techniques. Two samples with average particle sizes 5 nm 20 nm, respectively, were studied. For both samples, the $\mu$SR results exhibit clear signatures superparmagnetic state at high temperature magnetically blo...

Superparamagnetic few-layer graphene nanocomposites (FLG- NCs) can be used for many technological applications, such as solar cells, batteries, touch panels and supercapacitors. In this work, we applied electrochemical exfoliation method as a simple, one step and economical technique to fabricate FLG- NCs. The fabricated Superparamagnetic FLG- NCs were characterized by X-ray diffraction (XRD), ...
