Toray Develops Porous Fiber Technology for Adsorbing Pathogenic Substances in Intractable Diseases

Toray Industries, Inc. announced the development of a technology that allows for the arbitrary control of pore sizes in polymethyl methacrylate (PMMA) porous fibers, ranging from several nanometers to approximately 1,000nm. This breakthrough enables the selective adsorption and removal of high-molecular-weight pathogenic substances, such as autoantibodies, lipoproteins, and exosomes, which were previously difficult to capture. The company intends to advance the design and mass production of these fibers for blood purification therapies for intractable diseases, including autoimmune disorders, cardiovascular metabolic diseases, neurodegenerative diseases, and cancer. Additionally, applications in biopharmaceutical manufacturing are being explored.
