Effect of SPIO Nanoparticle Concentrations on Temperature Changes for Hyperthermia via MRI

الملخص EN

Magnetic nanoparticles (MNPs) are being developed for a wide range of biomedical applications.

In particular, hyperthermia involves heating the MNPs through exposure to an alternating magnetic field (AMF).

These materials offer the potential for selectively by heating cancer tissue locally and at the cellular level.

This may be a successful method if there are enough particles in a tumor possessing sufficiently high specific absorption rate (SAR) to deposit heat quickly while minimizing thermal damage to surrounding tissue.

The current research aim is to study the influence of super paramagnetic iron oxides Fe3O4 (SPIO) NPs concentration on the total heat energy dose and the rate of temperature change in AMF to induce hyperthermia in Ehrlich carcinoma cells implanted in female mice.

The results demonstrated a linearly increasing trend between these two factors.
