| 摘 要： | In the present study,morphology,size distribution,structure,biocompatibility and magnetic properties of potassium ferrite nanoparticles(KFeO_2 NPs),synthesized by conventional sol—gel method have been reported.The formation of spherical nanoparticles with orthorhombic structure has been confirmed by scanning electron microscopy and X-ray diffraction.The particle size,as obtained by transmission electron microscopy has been found to be in the range of 4—7 nm.Further,the size distribution has been scrutinized using Analyse-it software,where a platykurtic feature in the size distribution was observed.Fourier transform-infrared spectroscopy and thermogravimetric analysis showed the formation of metal(Fe,K) bonds at Neel temperature of 337℃.Vibrating sample magnetometer analysis revealed the superparamagnetic behaviour of the synthesized KFeO_2NPs,with saturation magnetization of 25.72 emu/g.In vitro cytotoxicity test,using MTT assay,on T cell lines(Jurkat cells) showed that KFeO_2 NPs are biocompatible at a particle concentration of 100 |j.g/ml.
