“…Analogous correlations can be found elsewhere. [47,48] Moreover, by performing such combined analysis, the amount of polymer induced by polymerization process can be easily deduced and consequently to polymerization conversion as illustrated in Table 1. [49] Firstly, it is interesting to notice that total polymerization conversions were observed leading to polymer formation on magnetic emulsion and polymer forming secondary nucleation.…”

International audienceMagnetic hybrid colloidal particles can be characterized using various techniques and numerous tools leading generally to particles size, size distribution, and electrokinetic properties. However, the chemical composition of these hybrid particles can be estimated using thermal gravimetric analysis (TGA). More interestingly, the combination of this quantitative technique with the magnetization measurement leads not only to chemical composition but also to the overall polymerization conversion and more precisely to the polymerization conversion on the seed particles. In fact, the TGA performed on dried magnetic particles leads to exact organic/inorganic chemical composition. Regarding the magnetization, the amount of magnetic material can be deduced, and consequently, the amount of non-magnetic material can be also estimated. Thus, TGA and magnetization measurements are considered as complementary techniques for characterization of magnetic hybrid colloidal particles

“…Examples of distinctive synthetic polymeric systems are: polyethylene glycol, poly(vinyl alcohol), poly(lactic- co -glycolic acid), poly(vinyl-pyrrolidone), poly(ethylene- co -vinyl acetate), etc 4. Natural polymer systems include the use of gelatin, pollutant, dextran chitosan, etc 88,89. In order to enhance dispersibility in an aqueous medium, various surfactants, such as sodium oleate, dodecylamine, and sodium carboxymethyl cellulose, are usually used 90.…”

Abstract:Recently, iron oxide nanoparticles (NPs) have attracted much consideration due to their unique properties, such as superparamagnetism, surface-to-volume ratio, greater surface area, and easy separation methodology. Various physical, chemical, and biological methods have been adopted to synthesize magnetic NPs with suitable surface chemistry. This review summarizes the methods for the preparation of iron oxide NPs, size and morphology control, and magnetic properties with recent bioengineering, commercial, and industrial applications. Iron oxides exhibit great potential in the fields of life sciences such as biomedicine, agriculture, and environment. Nontoxic conduct and biocompatible applications of magnetic NPs can be enriched further by special surface coating with organic or inorganic molecules, including surfactants, drugs, proteins, starches, enzymes, antibodies, nucleotides, nonionic detergents, and polyelectrolytes. Magnetic NPs can also be directed to an organ, tissue, or tumor using an external magnetic field for hyperthermic treatment of patients. Keeping in mind the current interest in iron NPs, this review is designed to report recent information from synthesis to characterization, and applications of iron NPs.

“…Due to primary amine groups, chitosan has been commonly preferred in pharmaceutical applications. 68 The results demonstrated that chitosan coated IONPs had superparamagnetic properties and they were suitable for biomedical applications. At basic or neutral pH conditions, chitosan is not water-soluble; however, in acidic pH amino groups are protonated, which make chitosan water-soluble.…”
