Magnetic Nanoparticles with High Specific Absorption Rate at Low Alternating Magnetic Field.
This paper describes synthesis and characterization of magnetic nanoparticles intended for tumor hyperthermia applications. It reports that the particles show relatively high specific absorption rate (22–200 W/g) under a 160 kHz alternating magnetic field at 100–500 Oe, despite low saturation magnetization. The abstract focuses on materials properties and heating performance rather than health risk assessment from environmental EMF exposure.
Key points
- The study develops gamma-FeO magnetic nanoparticles with carboxymethyl-dextran coating.
- Primary particle crystals are reported as 2–4 nm, forming 20–40 nm aggregates.
- The coated particles have a reported zetasize of 110–120 nm.
- Saturation magnetization is reported as low (1.5–6.5 emu/g).
- Specific absorption rate is reported as 22–200 W/g under 160 kHz alternating magnetic field exposure.
- Applied field strengths in the measurements are reported as 100–500 Oe.
