The actuality of the research is defined by the need of creation means for wound treating, the insufficient development of methods of the use of the possibilities of modern nanomaterials. The purpose is to substantiate the possibility of creating materials of a given structure to ensure controlled liquid removal using magnetic nanocomponents. The research involved methods of solving the nonlinear diffusion equation, macroexperiments on liquid sorption by materials filled with nanocomponents. The main approaches and boundary conditions for solving nonlinear equations are substantiated. The approximate analytical solution of the diffusion equation clearly highlighted the possibility of finding the basic diffusion coefficient and the inhibition coefficient, which determines the nonlinear nature of the sorption process. Two experiments register the liquid reaching the opposite surface of the healing material and the mass of the accumulated liquid at a certain time. It has been proven that the introduction of magnetic nanocomponents into the structure of medical materials affects the sorption processes. The addition of magnetic nanocomponents at the initial moment reduces the diffusion coefficients. At the same time, the content of such components increases the bacteriostatic properties of the material. The organisation of the sorption process in the conditions of a variable magnetic field significantly affects the sorption process. An increase in the magnetic field strength significantly increases the diffusion coefficient and decreases the braking coefficient. The dependence of the diffusion coefficients on the content of nanocomponents and the strength of the magnetic field is given in the article. These data make it possible to predict the diffusion properties of the material, as well as to determine the process parameters that provide the specified sorption parameters. The practical value is determined by the possibility of creating materials for the treatment of wounds with adjustable intensity of exudate removal
