Introducing a Polypyrrole (PPy)-Manganese Ferrite (MnFe2O4) Nanocomposite Based Microwave Absorber for Studying the Effect of the Radiation on the Modification of the Patient’s Functional State

In the present work, polypyrrole (PPy)-manganese ferrite (MnFe2O4) nanocomposite based microwave absorber for studying the effect of the radiation on the modification of the patient’s functional state is reported. X-ray powder diffraction (XRPD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) images are used to characterize the prepared nanocomposites. Recently, new microwave-based imaging and hyperthermia applications have emerged in the field of diagnostics and therapy. This technology involves the application of low power microwaves, utilising contrast between the relative permittivity of tissues to identify pathologies. This contrast can be further enhanced through the implementation of nanomaterials. For therapy, this technology can be applied in tissues either through hyperthermia. Nanomaterials can absorb electromagnetic radiation and can enhance the microwave hyperthermic effect. Microwave generators of super-low intensity in the centimeter wavelength range at a power level not exceeding 1 μW/cm2 have been successfully used in experimental and clinical medicine. In the present work, we have implemented a project aimed at the development of a modular-type technical system designed to generate microwave radiation with specified properties. This article presented the electrophysiological efficiency of super-low intensity radiation in the centimeter range of wavelengths modulated by low-frequency signals similar to the EEG rhythm with cyclical variability of the duty cycle.
