“…This behavior of the magnetic filler is similar to the action of an external field that induces a magnetic ordering in the range of the Curie temperature, which was previously observed in a bulk ferrimagnet [41]. It should be noted that the methods used for the analysis of Mössbauer spectra of nanoparticles in a weak magnetic field within the framework of the three-level model upon multi-level relaxation and described in [38][39][40] significantly extend the capabilities of Mössbauer spectroscopy for the characterization of magnetic nanomaterials.…”

“…The complete destruction of magnetic hyperfine fields at temperatures well below the Curie point is observed in very small magnetic particles. The most appropriate approach to the physical description of the spectral transformations is provided by the multi-level relaxation model (MLRM) [38][39][40] based on the quantum-mechanical description of single-domain particles. The mathematical analysis of the spectrum (Table 1) out using the special program [28].…”

Hybrid ceramics consisting of hydroxyapatite Ca 10 (PO 4 ) 6 (OH) 2 and ferrite Fe 3 O 4 were synthesized using a two-stage procedure. The first stage included the synthesis of Fe 3 O 4 ferrite particles by co-precipitation and the synthesis of hydroxyapatite. In the second stage, the magnetic hybrid hydroxyapatite-ferrite bioceramics were synthesized by a thorough mixing of the obtained powders of carbonated hydroxyapatite and Fe 3 O 4 ferrite taken in a certain proportion, pressing into tablets, and annealing in a carbon dioxide atmosphere for 30 min at a temperature of 1200°C. The properties of the components and hybrid particles were investigated using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Mössbauer spectroscopy. The saturation magnetization of the hybrid ceramic composite containing 20 wt % Fe 3 O 4 was found to be 12 emu/g. The hybrid hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 )-ferrite Fe 3 O 4 ceramics, which are promising for the use in magnetotransport and hyperthermia treatment, were synthesized and investigated for the first time.

“…As for the diffraction angles of the bimetallic nanomaterial, the characteristic peaks lie at 44.5° (broad peak), 50.7°, 65.0°, and 74.3°. The diffraction peaks of Cu NPs are similar to those of pure bulk crystalline copper, in terms of angular positions but they are relatively broad, as the mean size of the particles is of the order of nanometers . A characteristic peak at 2 θ ∼44.7° in the XRD pattern of Fe NPs indicates its presence, predominantly in the Fe 0 state.…”

Three metallic nanomaterials, i.e., iron, copper, and bimetallic iron-copper were easily synthesized using a wet-chemical method and were properly characterized. The materials were tested against two bacterial strains, Staphylococcus aureus and Escherichia coli in order to evaluate their antibacterial activity, as well as their biofilm formation inhibition properties. The total inhibition of bacterial growth, at low mg/mL concentrations, implies the satisfactory antibacterial activity of the nanomaterials against bacteria. Between the two bacterial strains used, E. coli is more susceptible to the effect of the nanomaterials than S. aureus. However, the results for the respective biofilms are significantly different since S. aureus biofilm formation is more easily inhibited. There are differences in the way of action against the two different bacteria and diverse mechanisms of action are proposed to justify them. Furthermore, positive 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical tests demonstrated that the nanomaterials are free-radical scavengers while TBARS (thiobarbituric acid reactive substances) tests evidenced their lipid oxidation inhibition properties, although at high concentration levels. Copper nanoparticles proved to be the most effective of the three materials tested, against DPPH radicals and lipid peroxidation followed by the Fe-Cu and lastly by the Fe nanoparticles. The intrinsic magnetic properties of iron-based materials can provide long-term benefits for antibacterial or anti-biofouling treatment in water purification systems as well as for antioxidant activity purposes.

“…High-resolution TEM (HRTEM), field-emission SEM (FESEM), and XRD techniques can measure size calculation. TEM is very helpful in achieving the determination of the crystallinity, aggregation state of NPs, lattice spacing, and electron phase shift ( Gabbasov et al, 2015 ; Chekli et al, 2016 ). The sharp peaks of XRD are easy to calculate the size of NPs which is done through the Scherrer equation.…”

Diverse applications of nanoparticles (NPs) have revolutionized various sectors in society. In the recent decade, particularly magnetic nanoparticles (MNPs) have gained enormous interest owing to their applications in specialized areas such as medicine, cancer theranostics, biosensing, catalysis, agriculture, and the environment. Controlled surface engineering for the design of multi-functional MNPs is vital for achieving desired application. The MNPs have demonstrated great efficacy as thermoelectric materials, imaging agents, drug delivery vehicles, and biosensors. In the present review, first we have briefly discussed main synthetic methods of MNPs, followed by their characterizations and composition. Then we have discussed the potential applications of MNPs in different with representative examples. At the end, we gave an overview on the current challenges and future prospects of MNPs. This comprehensive review not only provides the mechanistic insight into the synthesis, functionalization, and application of MNPs but also outlines the limits and potential prospects.
