Magnetic Nanoparticle Hyperthermia Using Pluronic-Coated Fe₃O₄ Nanoparticles: An In Vitro Study

Figure 1

Dependence of magnetic field strength on specific absorption rate (SAR) of Pluronic-coated magnetic nanoparticles (open circles). Energy efficiency of applied magnetic field to generate self-heating (closed circles). The temperature rise was divided by 𝐻²×𝑓, where 𝐻 and 𝑓 are the amplitude and frequency of applied ac magnetic field, respectively. The ac field frequency was 210 kHz, and the amplitude was varied from 4 to 20 kA/m (50 to 250 Oe).
