“…1,2 Magnetic microspheres with tailored functional polymer shells have attracted special attention. Both synthetic and natural polymers, such as PEG, 12,28 chitosan, 19 alginate, 29,30 dextran, 31 poly(vinylpyrrolidone) (PVP) 32 or poly(vinyl alcohol) (PVA), 33 have been used to stabilize Fe 3 O 4 microspheres, offering long-term stability and biocompatibility. Different natural polymers are considered as the preferred choice because of their better biocompatibility, nontoxicity and easy conjugation with various functional groups.…”

“…Citric and tartaric acids, in addition to oleic acid, are utilized to stabilize FFs within a wide range of pH (pH 3–11) [ 85 ]. Polymers such as silica [ 86 ], chitosan [ 87 ], polyvinyl alcohol (PVA) [ 88 ], and ethylene glycol [ 89 ] are commonly employed to coat nanoparticles and to prevent them from sticking together, thus improving aqueous medium dispersibility. To avoid oxidation, anti-oxidant compounds might be added.…”

Magnetite nanoparticles with different surface coverages are of great interest for many applications due to their intrinsic magnetic properties, nanometer size, and definite surface morphology. Magnetite nanoparticles are widely used for different medical-biological applications while their usage in optics is not as widespread. In recent years, nanomagnetite suspensions, so-called magnetic ferrofluids, are applied in optics due to their magneto-optical properties. This review gives an overview of nanomagnetite synthesis and its properties. In addition, the preparation and application of magnetic nanofluids in optics, nanophotonics, and magnetic imaging are described.

“…It is necessary to select the dispersant very carefully by keeping in view its properties should match with carrier liquids for example silica, Chitosan, ethylene glycol (EG) polyvinyl alcohol (PVA), Polyvinylpyrrolidone (PVP), Poly acrylic acid (PAA), and gelatin [76]. These stabilizers decrease the toxic effect prevent the surface oxidation increased the biocompatibility, bio-adhesion colloidal stability and give rise the uniformly disperse particles [77][78][79][80]. These types or ingredients are essentials for the ferrofluid synthesized by either water-based media or organic based media.…”

The study of magnetic nanoparticles (MNPs) is an emergent field of science in this era due to their widespread utilization in the various fields of biomedical science. Developing concerns of magnetic nanoparticles in the researcher’s field led to design a huge number of MNPs including individual or binary metallic particles, oxides, (ferrites), biopolymer coated composites, metallic carbides and graphene mediated nanoparticles. Numerous synthetic routes are defined in literature to attain the desired size, crystal structure, morphology and magnetic properties. To build up biocompatibility, MNPs subjected to surface treatments by coating with some suitable organic or inorganic biomaterials which not only improves its physical characteristics but also elevate its chemical stability. These biomaterials coat either isolatly or in a combined state to enhance the colloidal stability, magnetic properties as well as prevent it cytotoxicity and surface corrosion in the biological media. These properties are essential for the particles and empowering their effectiveness in various biomedical science i.e., drug delivery Magnetic resonance imaging (MRI), hyperthermia, biosensors and gene therapy etc. Current review recapitulates the verdicts of previous research on the subject of magnetic nanoparticles. It will also explain the recent advancements of biomaterials that execute a dynamic role in various medical treatments. Our main focus is to report the particle types, design and properties as well as discussing various synthetic routes including sol gel, co-precipitation, microemulsion, green synthesis, sonochemical method and polyol synthesis etc. These methods produced particles of excellent yield with unique magnetic properties, coercivity and crystallinity and enhanced biocompatibility as compared to traditional methods used to develop MNPs.
