Toray Develops Porous Fibers for Adsorbing Pathogenic Substances in Intractable Diseases

Toray Industries, Inc. has developed a technology to control the pore size of polymethyl methacrylate (PMMA) porous fibers within a wide range from several nm to approximately 1,000nm. This breakthrough allows for the selective adsorption of pathogenic substances associated with intractable diseases such as autoimmune disorders, cardiovascular metabolic diseases, neurodegenerative diseases, and cancer. By utilizing advanced analysis and digital simulation, Toray has achieved significantly larger pore sizes while maintaining fiber strength. The company is advancing the design and mass production technology for various disease treatments, aiming for early practical application and potential expansion into biopharmaceutical manufacturing.
