“…When cells were treated with CoFe 2 O 4 calcined at 800 °C or NiFe 2 O 4 calcined at 800 °C, the majority of cells displayed features of live cells: they appeared dark, fibrous in shape, and adherent to the well. In these materials, the most significant source of toxicity that could influence the cell viability was the dissolution of Co 2+ , Ni 2+ , and Fe 3+ ions from the surface of the NPs, which then could interact with the cells. , The described XRD and XPS results demonstrate that the CoFe 2 O 4 NPs that were calcined at 400 °C and the NiFe 2 O 4 NPs that were calcined at 250 °C had more defect sites at their surface as a result of their lower crystallinity, which was also supported by our TEM analysis. Moreover, TEM results revealed smaller NP sizes for the samples calcined at lower temperatures.…”

“…Both hard and soft magnetic nanomaterials have been proved to be promising candidates for applications such as biosensors, drugs carriers, or contrast agents in magnetic resonance . However, their widespread use has been hampered by their toxicity due to the remarkable amount of cobalt (Co 2+ ) or nickel (Ni 2+ ) release in aqueous solutions, aggregation in solution, and poor accessibility of the surface when surfactants are used during their synthesis. , Even though many studies have focused on the biomedical applications of CoFe 2 O 4 and NiFe 2 O 4 NPs, the knowledge over how various physical and chemical parameters influence their cytotoxicity remains limited.…”

CoFeO and NiFeO nanoparticles (NPs) represent promising candidates for biomedical applications. However, in these systems, the knowledge over how various physical and chemical parameters influence their cytotoxicity remains limited. In this article, we investigated the effect of different calcination temperatures over cytotoxicity of CoFeO and NiFeO NPs, which were synthesized by a sol-gel proteic approach, toward L929 mouse fibroblastic cells. More specifically, we evaluated and compared CoFeO and NiFeO NPs presenting low crystallinity (that were calcined at 400 and 250 °C, respectively) with their highly crystalline counterparts (that were calcined at 800 °C). We found that the increase in the calcination temperature led to the reduction in the concentration of surface defect sites and/or more Co or Ni atoms located at preferential crystalline sites in both cases. A reduction in the cytotoxicity toward mouse fibroblast L929 cells was observed after calcination at 800 °C. Combining with inductively coupled plasma mass spectrometry data, our results indicate that the calcination temperature can be employed as a facile strategy to reduce the cytotoxicity of CoFeO and NiFeO, in which higher temperatures contributed to the decrease in the dissolution of Co or Ni from the NPs. We believe these results may shed new insights into the various parameters that influence cytotoxicity in ferrite NPs, which may pave the way for their widespread applications in biomedicine.

“…In the present research, in order to omit Ag NPs of environment that is limited in the use of them and increase the antibacterial Ag NPs, a novel kind of three‐component magnetic nanocompound with a core/shell/shell structure called NiFe 2 O 4 @ABS@Ag was developed. NiFe 2 O 4 was synthesised by employing the citrate‐gel method [10, 11]; then it was coated with the ABS polymer to obtain the NiFe 2 O 4 @ABS compound. As the final step, Ag NPs provided by the reduction of Ag + ions were convened in the surface of the NiFe 2 O 4 @ABS composite in order to obtain the final NiFe 2 O 4 @ABS@Ag nanocompound.…”

The present research attempted to characterise the structural and magnetic characteristics of NiFe 2 O 4 @ABS@Ag nanoparticles (NPs) made of nickel ferrite (NiFe 2 O 4), acrylonitrile butadiene styrene (ABS) and silver NPs (Ag NPs), this was done by employing techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy, as well as a vibrating sample magnetometer. The XRD patterns obtained indicated that following ABS and Ag NPs coating, the crystallite size (from Scherrer formula) was increased from 32 to 40 nm. It was confirmed by the magnetic measurements that the maximum magnetisation of the NiFe 2 O 4 core was dropped when the surface was coated with ABS and Ag NPs. The antimicrobial activity of this three-component nanocomposite was tested, showing that the nanocomposite NiFe 2 O 4 @ABS@Ag could be isolated from a water solution by using a magnet.

“…Nickel magnetic nanoparticles are of great interest due to their superparamagnetic and optical properties. There have been many protocols for the synthesis of cobalt or nickel magnetic nanoparticles, which include thermal decomposition, reverse micelles, chemical reduction, and polyol reduction, and for cobalt magnetic nanoparticles also sonochemical synthesis [54][55][56][57][58][59][60][61][62]. There are also many alloy-bimetallic magnetic nanoparticles that include various systems, such as iron-cobalt, nickel-cobalt, iron-platinum, and cobalt-platinum.…”

Two types of micro-and nanocarriers for immobilization of enzymes for biotechnological and biomedical applications are described: magnetic nanoparticles and crosslinked enzyme aggregates (CLEAs). Nanosized structures with their large surface and smaller size volume ratio, which is dependent on their strong magnetic dipole, give key features that make magnetic nanoparticles useful in many biotechnological and biomedical applications. They are therefore used as carriers to which different active substances can bind. The preparation of the magnetic nanoparticles, possible surface coating methods, and functionalization with different materials are described. Enzyme immobilization methods, such as adsorption, affinity binding, chelation, or metal binding or covalent binding, enable the preparation of efficient and stable enzyme bound to magnetic nanoparticles. Such a product may be used among bioreactor applications for targeted drug delivery in biosensors or bioimaging and magnetic resonance imaging. Preparation of CLEAs, the microsized enzyme structures without a carrier, is described as well. Their main advantage is very simple preparation, where two steps, precipitation of the enzyme and cross-linking, are joined. A broad spectrum of enzymes for CLEA preparation has been used and many biotechnological reactions are catalyzed. The improvement in CLEA preparation to enhance their stability and operability is also shown.
