Superparamagnetic iron oxide nanoparticles with highly nonlinear magnetic behavior are attractive for biomedical applications like magnetic particle imaging and magnetic fluid hyperthermia. Such particles display interesting magnetic properties in alternating magnetic fields and here we document experiments that show differences between the magnetization dynamics of certain particles in frozen ...

The present study reports on the preparation and the cell viability assay of two nanoemulsions loaded with magnetic nanoparticle and chloroaluminum phthalocyanine. The preparations contain equal amount of chloroaluminum phthalocyanine (0.05 mg/mL) but different contents of magnetic nanoparticle (0.15 10 or 1.50 10 particle/mL). The human bone marrow mesenchymal stem cell line was used as the mo...

Introduction The human body naturally uses heat to fight disease. For example, viruses and bacteria proliferate at normal body temperatures, so the body instinctively defends itself by increasing its temperature several degrees to slow the rapid multiplication of such disease-causing agents. This phenomenon, commonly called a fever, gives the body an advantage while fighting the infection. Feve...

Two different types of magnetic nanoparticles (MNPs) were synthesized in order to compare their efficiency as radioactive vectors, Fe₃O₄-Naked (80 ± 5 nm) and polyethylene glycol 600 diacid functionalized Fe₃O₄(Fe₃O₄-PEG600) MNPs (46 ± 0.6 nm). They were characterized based on the external morphology, size distribution, and colloidal and magnetic properties. The obtained specific power absorpti...

Synthesis of ultrafine magnetic nanoparticles with different chemical compositions is essential to study the fluid hyperthermia (MFH) as a treatment in which superparamagnetic behaviour materials beneficial. In this paper, x and y amounts were synthesized find out tuning pattern for properties, especially anisotropy constant gain best heating efficiency. We proved that co-presence ions will gre...

Branched or multiply branched iron oxide nanoparticles are synthesized, the crystal domains rearrange forming single crystalline structures, that is crucial for efficient magnetic hyperthermia.

The Fe3O4@mSiO2 nanocarrier that consisted of a magnetic Fe3O4 nanoparticle core and a mesoporous silica (mSiO2) shell was synthesized. It shows a uniform sphere morphology about 65 nm in diameter. Considering the magnetic hyperthermia of Fe3O4 under an alternating magnetic field (AMF), a thermo-sensitive polymer, poly[(ethylene glycol)-co-(L-lactide)] (P(EO-co-LLA)), was used as "gatekeeper" c...
