Structural and magnetic properties of starch-coated magnetite nanoparticles
TLDR
In this article, the structural and magnetic properties of magnetic Fe3O4 nanoparticles are studied by means of X-ray diffraction, transmission electron microscopy (TEM), Raman spectrum, Fourier Transform Infrared (FT-IR), and a Vibrating Sample Magnetometer (VSM).Abstract:
Magnetic Fe3O4 nanoparticles are prepared by the coprecipitation method and coated with starch as a surfactant. Their structural and magnetic behaviours are studied by means of X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), Raman spectrum, Fourier Transform Infrared (FT-IR) as well as with a Vibrating Sample Magnetometer (VSM). The magnetic Fe3O4 nanoparticles under investigation have an average size of about 14 nm. The coated magnetic nanoparticles exhibit super-paramagnetic behaviours with a blocking temperature of about 170 K and saturation magnetisation ranging between 30 and 50 emu g−1. In addition, the results of FT-IR indicated that interactions between the Fe3O4 particles and starch layers are much improved.read more

Development of functionalized superparamagnetic iron oxide nanoparticles for interaction with human cancer cells
TL;DR: The successful development of functionalized SPION displaying potential cellular uptake by human cancer cells depends both on the presence of amino groups on the coating shell of the nanoparticles and of its ratio to the amount of iron oxide.
