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 nm to approximately 1,000nm. This technology enables the selective adsorption of pathogenic substances that were previously difficult to remove, contributing to new blood purification treatment options for autoimmune diseases, cardiovascular metabolic disorders, neurodegenerative diseases, and cancer. Leveraging its expertise in PMMA, which has a 50-year track record in blood purification, Toray plans to advance the design and mass production of these fibers for various clinical applications and biopharmaceutical production.
