| Abstract Scope |
A broad spectrum of nanomaterials has been investigated for multiple purposes in recent years. Magnetic nanoparticles (MNPs), such as Iron oxide nanoparticles and superparamagnetic iron oxide nanoparticles have received attention because of their physicochemical and magnetic properties and their ease of combination with a polymeric matrix. Furthermore, the arresting of these MNPs into a cross-linked matrix known as hydrogel has attracted significant interest in the biomedical field. Commonly, MNPs act as a reinforcing material for the polymer matrix. In the present work, several methods, such as co-precipitation, polyol, hydrothermal, microemulsion, and sol-gel methods, are reported to synthesize MNPs with controllable physical and chemical properties that suit the required application. Due to the potential of magnetite-based nanocomposites, specifically in hydrogels, processing methods, including physical blending, in situ precipitation, and grafting methods, are exhibited. Moreover, the most common characterization techniques employed to study MNPs and magnetic gel are discussed. |
