Magnetic Control of Light Transmission and of Electrical Conductivity in (Hybrid) Magnetorheological Suspensions Based on Bioactive Components

摘要

Bio-magnetic active suspensions and tissues are manufactured from honey, cotton fibers and various concentrations of carbonyl iron (ΦCI) microparticles. The obtained (h)MRSs composites are examined as magnetoactive materials for industrial and therapeutic applications. We propose a new experimental design, and show that the light transmission through (h)MRSs and the electrical conductivity are sensibly influenced by the intensity H and gradient δ of an external magnetic field, as well as by ΦCI. These effects make (h)MRSs versatile candidates in fabrication of technical and medical devices and equipment which require a magnetic control of the light transmission and of the thermal transport of bioactive components. They can be used for various applications such as scaffolding biomaterials for tissue repair and regeneration or in the quality control of honey crystallization and of its derivative products in industrial processes.
