Mathym is a nanotechnology company dedicated to the development, manufacturing and commercialization of innovative nanomaterials called colloidal solutions.
Colloidal solutions consist in nanoparticles in suspension in liquids (solvents, monomers, water or alcohols). Depending of the type and nature of the nanoparticles, many innovative characteristics and properties can be conferred to the final colloidal solution.
Mathym’s first developments have led to colloidal radiopacifiers to be used in biomedical materials such as dental or orthopedic composites. Mixed with Mathym’s colloidal solutions, the latter acquire radio-opacity quality and then become X-ray visible. Its first colloidal radiopacifiers are lanthanide fluoride based.
The strategic rationale of Mathym is either to target markets using dry nanomaterials (such as radiopacifying nano-powders) that engenders various industrial use constraints because of the nanoparticles high volatility / tough handling or to participate to collaborative R&D projects focused on groundbreaking innovative nanomaterials dedicated to the life sciences applications – and more especially on imaging subjects.
Mathym emerged from academic research based at Lyon University and benefits from strong and exclusive industrial property. The company was founded in September 2013 by Julien Alberici and Frederic Chaput, respectively acting as CEO and CSO. 8 employees currently work in Mathym, including PhDs in Chemistry and Process engineers


Half of Mathym's staff is composed of Researchers. As of today, 8 people are working at MATHYM, of which 4 are PhD (organic or inorganic chemistry) and 1 is a process engineer.
