“…It means that for magnetite nanoparticles covered with TBAOH the critical size is slightly below 8 nm. It has been reported that the paramagnetic doublet can be observed for the magnetite particles smaller than 10 nm embedded in a polymer matrix [9]. The difference in the magnetic behavior of the particles can have an origin in strength of dipole interaction between particles in different matrices.…”

The magnetite nanoparticles were prepared by modified Massart's method in water and in alcohol. The influence of the condition of preparation on the properties of magnetite nanoparticles were investigated by Mössbauer spectroscopy. The size of the particles were determined by transmission electron microscopy. It was shown that the particles size in the alcoholic reaction is smaller than in aqueous reaction. Moreover, the increase in the reaction time improves the stoichiometry of magnetite nanoparticles.

“…[1] The inclusion of carbon nanostructures, metallic, magnetic, and semiconducting nanoparticles in polymer matrices has been investigated for a wide range of applications. [2][3][4][5][6][7][8][9][10][11][12][13][14] Electromagnetic interference (EMI) is a known problem in electronic circuits, and there is a critical need for developing versatile and effective EMI-shielding materials. Conducting polymers such as polyaniline (PANI) and polypyrrole (PPy) have been identified as good candidates for this application.…”

Magnetic nanoparticles embedded in polymer matrices are good examples of functional nanostructures with excellent potential for applications such as electromagnetic interference shielding, magneto‐optical storage, biomedical sensing, flexible electronics, etc. Control over the dispersion of the nanoparticle phase embedded in a polymer matrix is critical and often challenging. To achieve excellent dispersion, competition between polymer–polymer and polymer–particle interactions have to be balanced to avoid clustering of particles in polymer nanocomposites. We report the first deposition of magnetic nanocomposite poly(methyl methacrylate)/polypyrrole bilayers from solution using spin‐coating. Fe3O4 nanoparticles have been synthesized using a chemical co‐precipitation route. Using a combination of dissolving the polymer and mixing fatty acid surfactant coated Fe3O4 nanoparticles, we have demonstrated the formation of nanocomposites with uniform nanoparticle dispersion. Cross‐sectional scanning electron microscopy, transmission electron microscopy, and magnetic measurements confirm the excellent dispersion and superparamagnetic response. Low‐frequency impedance measurements on these bilayers are also presented and analyzed.

“…[64] In contrast, many researchers have reported efficient routes for the synthesis of monodispersed MNPs by adding surfactants such as dextran or PVA in the reaction media to have better control of the size distribution. [65] Influence of surfactants on the structural and magnetic properties of NPs have been studied [66] and it was concluded that the estimated average particle and crystallite size distributions depend on the choice of the surfactant. This method allows coating the produced MNPs to make them stabilized and biocompatible especially for biomedical applications.…”

In order to translate nanotechnology into medical practice, magnetic nanoparticles (MNPs) have been presented as a class of non‐invasive nanomaterials for numerous biomedical applications. In particular, MNPs have opened a door for simultaneous diagnosis and brisk treatment of diseases in the form of theranostic agents. This review highlights the recent advances in preparation and utilization of MNPs from the synthesis and functionalization steps to the final design consideration in evading the body immune system for therapeutic and diagnostic applications with addressing the most recent examples of the literature in each section. This study provides a conceptual framework of a wide range of synthetic routes classified mainly as wet chemistry, state‐of‐the‐art microfluidic reactors, and biogenic routes, along with the most popular coating materials to stabilize resultant MNPs. Additionally, key aspects of prolonging the half‐life of MNPs via overcoming the sequential biological barriers are covered through unraveling the biophysical interactions at the bio–nano interface and giving a set of criteria to efficiently modulate MNPs' physicochemical properties. Furthermore, concepts of passive and active targeting for successful cell internalization, by respectively exploiting the unique properties of cancers and novel targeting ligands are described in detail. Finally, this study extensively covers the recent developments in magnetic drug targeting and hyperthermia as therapeutic applications of MNPs. In addition, multi‐modal imaging via fusion of magnetic resonance imaging, and also innovative magnetic particle imaging with other imaging techniques for early diagnosis of diseases are extensively provided.
