Magnetic iron oxide nanoparticles (IONPs) have gained momentum in the field of biomedical applications. They can be remotely heated via alternating magnetic fields, and such heat transferred from IONPs to local environment. However, microscopic mechanism transfer is still debated. By X-ray total scattering experiments first-principles simulations, we show how occur. After establishing structura...

UNLABELLED A one-step process for the production of nanoparticles presenting advanced magnetic properties can be achieved using vapor condensation. In this article, we report on the fabrication of Fe particles covered by a uniform MgO epitaxial shell. MgO has a lower surface energy than Fe, which results in a core-shell crystal formation. The particles satisfy a few of technical requirements fo...

Introduction Magnetic oxide nanomaterials, including iron oxide (Fe3O4 and γ-Fe2O3), spinel ferrites (MFe2O4; M=Mn, Zn, Cr, Ni, or Co) and hexagonal ferrite (MFe12O19, M=Ba and Sr) are attracting much attention due to their wide application potentials in advanced magnets, electronic devices, information storage, magnetic resonance imaging (MRI), and drug-delivery technology [1-6]. Hence, the sy...

A new paradigm in cancer theranostics is enabled by safe multifunctional nanoplatform that can be applied for therapeutic functions together with imaging capabilities. Herein, we develop a multifunctional nanocomposite consisting of Graphene Oxide-Iron Oxide -Doxorubicin (GO-IO-DOX) as a theranostic cancer platform. The smart magnetic nanoplatform acts both as a hyperthermic agent that delivers...

In magnetic nanoparticle hyperthermia treatment, the ideal objective is to destroy all tumor cells without any damage to neighboring normal tissues. Thus, the temperature distribution in cancerous tissue and also surrounding healthy tissues should become closer to the desired distribution. In this paper, the temperature distribution is estimated by using a numerical scheme to solve the Penne’s ...

Superparamagnetic magnetite nanoparticles (MNPs), Fe3O4, were synthesized via the modified coprecipitation method. The morphology of these MNPs is polyhedral. The particle size of MNPs ranged from 20 to 100 nm. For combined hyperthermia and thermoresponsive drug delivery applications, the heating element, MNPs, in the core of drug carriers should increase the temperature of the target up to 43 ...

Magnetic nanocrystals have been investigated extensively in the past several years for several potential applications, such as information technology, MRI contrast agents, and for drug conjugation and delivery. A specific property of interest in biomedicine is magnetic hyperthermia-an increase in temperature resulting from the thermal energy released by magnetic nanocrystals in an external alte...

As a fast developing alternative of traditional therapeutics, photodynamic therapy (PDT) is an effective, noninvasive, nontoxic therapeutics for cancer, senile macular degeneration, and so on. But the efficacy of PDT was compromised by insufficient selectivity and low solubility. In this study, novel multifunctional silica-based magnetic nanoparticles (SMNPs) were strategically designed and pre...
