Polyethylene Glycol Coated NiFe۲O۴ Nanoparticles Produced by Solution Plasma Method for Biomedical Applications

The structural and magnetic properties of the polyethylene glycol (PEG) coated nickel spinel ferrite (NiFe۲O۴) nanoparticles have been reported in the present study. NiFe۲O۴ nanoparticles were prepared by solution plasma method using KOH + Na۲Co۳ as electrolyte. The prepared powder of nickel ferrite nanoparticles was annealed at ۸۰۰ ˚C for two h and used for further study. The X-ray analysis confirmed the formation of a cubic spinel single-phase structure. The crystallite size, lattice parameter, and X-ray density of the PEG-coated NiFe۲O۴ nanoparticles were calculated using XRD data. TEM and FTIR studies revealed the presence of PEG on nickel ferrite nanoparticles and reduced agglomeration in the NiFe۲O۴ nanoparticles. The pulse-field hysteresis loop tracer technique studied the magnetic properties at room temperature. The magnetic parameters such as saturation magnetization, remanence magnetization, and coercivity have been obtained. These magnetic parameters were get decreased by PEG coating.
