    Hyperthermia properties of magnetic polyethylenimine core/shell nanoparticles: influence of carrier and magnetic field strength

  • Original language description

    Core/shell nanoparticles of magnetic polyethylenimine (MPEI) were prepared by one-step co-precipitation process. MPEI were precipitated by mixing Fe2 /Fe3 solution with polyethylenimine under basic media. The morphology, hydrodynamic size and the phase of the prepared magnetic nanoparticles were characterized using SEM, DLS and XRD, respectively. In addition, the functionality, thermal stability and magnetic properties were assessed using FTIR, TGA and VSM, respectively. The prepared magnetic nanoparticles able to generate local heat under alternative magnetic field caused by the delay in magnetic relaxation provide a benefit in cancer treatment. The strength effects of the applied magnetic field and the different viscosity carriers, namely water and ethanol, on the heating ability were investigated. It was an obvious rise of temperature by increasing in strength of applied magnetic field and by the exposure time. Heat transfer to the fluid was hindered by the viscosity of the carrier. The viscosity affects the heating properties through a Brownian mechanism and thus causes a significant specific absorption rate (SAR). The heating properties of the prepared MPEI nanoparticles with the highest SAR value (177.48 Wg−1) show their potential in hyperthermia application.
