![]() Results and DiscussionĬobalt (II) ferrite and composite materials synthesis was carried out in one stage with the formation of CoF 2O 4 and an in situ organic–inorganic composition. Therefore, the main goal of the study is to investigate the possibility of using simply the sol–gel technology to obtain cobalt (II) ferrite magnetic nanoparticles and composite organo–inorganic materials based on them. Finally, the mixture was calcined at 400 ☌ for 2 h in a muffle furnace. Then, the resulting transparent sol was dried at a temperature of 95 ☌ for 12 h. The mixed solution was heated in a water bath at 95 ☌ for 3 h. For example, in, transition metal salts were dissolved in deionized water, citric acid was added, and stirred for 1 h. Often these processes are lengthy and time-consuming. One of the promising methods for obtaining magnetic nanoparticles is the sol–gel method. The nanoparticles’ developed surface displays an increased adsorption activity, which can be used for organic–inorganic composite materials synthesis. Iron oxide compounds exhibit antibacterial properties and are nontoxic, which allows them to be considered as promising materials for theranostics. ![]() Ferrites transition elements are promising candidates for medical applications due to a successful combination of their technical parameters: ease of synthesis and presence of magnetic properties. The formation of dual-use materials containing an inorganic magnetic part and an organic one will expand the functional capabilities of substances. Study of the processes of synthesis of organo–inorganic composites is an interesting and challenging task. The possibilities of non-surgical and drug-free direct selective influence on individual cells in an external magnetic field by oscillations of magnetic nanoparticles fixed on the cell membranes or introduced into cells have been investigated. Interventional procedures are widely used, such as transarterial chemoembolization, catheter intra-arterial delivery of nanoparticles, etc. Research in the field of medicine is becoming more and more interdisciplinary, new methods of treatment are created. ![]() Consequently, wide possibilities for polyfunctional materials synthesis open up for various applications in medicine.Īn increase in the technogenic load on an individual in modern society leads to the development of many diseases, including cancer. The resulting composite materials have sufficient magnetic properties to be mobile in a magnetic field. Materials with a developed surface are formed: the surface area measured by the BET method is 83–143 m 2/g. Composite materials formation is established to lead to a significant (5–9 times) increase in the sample surface area. ![]() The fundamental possibility of obtaining an organo–inorganic composite material based on cobalt (II) ferrite and an organic carrier using the presented method has been proved. A composite materials formation mechanism is proposed, which includes a gelation stage where transition element cation chelate complexes react with citric acid and subsequently decompose under heating. The obtained materials were characterized using X-ray phase analysis, scanning and transmission electron microscopy, Scherrer, Brunauer–Emmett–Teller (BET) methods. The article presents results for the magnetic nanoparticles sol–gel method synthesis of cobalt (II) ferrite and organic–inorganic composite materials based on it.
