Biomagnetism today: basics and applications — •Galina V. Kurlyandskaya1,2 and Alexander P.

The last decade has seen a dramatic increase in research and applications of magnetic materials for biology and medicine. This work summarizes basics and recent developments in the areas of potential applications of magnetic nanomaterials in biomedicine and existing requirements for such applications. Special attention will be paid for the description of modern bionanomaterials: magnetic nanoparticles, ferrofluids, ferrogels, materials for magnetic biosensors. Magnetic biosensors are compact analytical devices incorporating a biological or biologically derived sensitive element, integrated in the physicochemical transducer employing a magnetic field and magnetic materials. Although existing devices allow a quantified evaluation of small changes in the magnetic susceptibility in the living system, or in magnetic field values created by the extracellular electric currents, there is a need to improve their sensitivity and specificity and further develop their design. Fabrication and characterization techniques for following magnetic nanomaterials will be discussed and examples of particular detection given. This work was supported by the RSF grant 18-19-00090.
