“…It is reported that the properties of ferrite nanoparticles (NPs) are affected by both composition and microstructure, which are influenced by their preparation technique [29]. Various methods have been utilized to synthesize cobalt ferrite MNPs incuding thermal decomposition [30,31], microemulsions [32,33], the sol-gel method [34,35], coprecipitation [36,37], the hydrothermal method [38], highenergy ball milling [39,40], and sonochemical synthesis [41,42]. Meanwhile, the major difficulty of these routes is the agglomeration of MNPs as well as their poor size control which limits their applications [43].…”

These days, magnetic nanoparticles (MNPs), especially cobalt ferrite MNPs, have attracted the attention of many scientists in many applications, e.g. cancer treatment, due to their good magnetic properties. In this study, firstly the Ni x Co1−x Fe2O4 MNPs (x = 0, 0.25, 0.5, and 0.75) were prepared through the sol–gel technique. The resulting particles were then coated with polyethylene glycol (PEG) polymer to obtain a core/shell structure. The x-ray diffraction and Fourier-transform infrared spectroscopy results illustrated that CoFe2O4 MNPs were successfully synthesized. Vibrating-sample magnetometer and (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bro-mide) assay results illustrated that the Ni0.5Co0.5Fe2O4 sample had the best saturation magnetization (71.68 emu g−1) and coercivity (∼500 Oe) values. Subsequently, the appropriate amount of PEG was found to be 15% wt/vol. The toxicity test showed that a concentration of 100 μg ml−1 of particles kept 96% of the cells alive. The particle size of the core/shelled MNPs was obtained to be ∼25 nm via a transmission electron microscopy image. Finally, it was observed that the Ni0.5Co0.5Fe2O4 sample coated with 15% wt/vol. PEG can be potentially used for hyperthermia.

“…Son yıllarda nanomanyetizma, bulk sistemlerdeki manyetizmadan önemli ölçüde farklı olduğu için hem temel hem de uygulamalı araştırmalarda ilgi görmektedir. (Ferrando 2016, Ebrahimi et al 2019, Binns 2014. Manyetik nanoalaşımlar, benzersiz manyetik özellikleri nedeniyle ultra yüksek yoğunluklu manyetik kayıt ortamı, manyetik veri depolama, radar emici malzeme, nükleer manyetik rezonans (NMR) görüntüleme, ilaç ve gen dağıtımı, kanser tedavisi ve teşhisi, tümörlerin ısıl tedavisi, hücre ayrımı, piller, floresan biyolojik etiketleme, gaz sensörleri ve katalizörler gibi endüstriyel ve biyomedikal uygulamalarda yaygın olarak kullanılmaktadır.…”
