Ukrainian Journal of Physics| Summary: | A structural model of cartilage tissue and the mechanism of influence of a magnetic field on the deformability of this tissue have been proposed. Proteoglycans are assumed to form layers whose surfaces are perpendicular to the direction of collagen fibers. The layers and the fibers are connected by adsorbed collagen chains. It has been shown that the magnetic field changes the arrangement of adsorbed chains. This leads to a change in the bending stiffness of the proteoglycan layers and, ultimately, a change in the deformability of the cartilage tissue as a whole. The proposed mechanism is testified making use of a model system. In the framework of this approach, the temperature dependences are obtained for the local shear compliance of a gelatin hydrogel subjected to a magnetic field. The experimental results agree with the proposed mechanism. |
