Mathym is a French nanotechnology company specializing in the development and industrialization of innovative colloidal solutions for the healthcare and optoelectronics sectors. Founded in 2013 and headquartered in Lyon, the company focuses on the synthesis of high-refractive index and radiopaque nanoparticles, including zirconia, ytterbium fluoride, and cerium oxide. Their proprietary liquid-phase synthesis platform enables the production of ultra-small, non-agglomerated particles that enhance the mechanical and optical properties of dental composites and biomedical materials. In 2019, Mathym was acquired by Baikowski, a global leader in high-purity alumina, to strengthen its position in the high-tech materials market. The company continues to operate as a specialized subsidiary, providing customized nanomaterials for global industrial partners.
