The company

More of 10 Years of research

The FIR – MED project, started in 2008, further to 15 years of researches on organic compounds analysis by infrared optical fiber, performed by glasses and ceramics team from the University of Rennes 1.

This work, conducted in collaboration with “iron and liver team” INSERM U991, helped to point out the relevance of the infrared fiber spectroscopy for tumoral or cirrhotic tissues analysis, and monitoring the development of bacteria.

DIAFIR was created in June 2011, to promote those results.

DIAFIR develops innovative systems based on chalcogenide fiberglass, a special glass with unique properties including infrared light transmission.

These glasses, biocompatible and hydrophobic, are ideal for the production of biosensors or probe that allow detecting changes in metabolic compositions.

Mid-infrared analysis was previously reserved for research due to its implementation and interpretation complexity. Henceforth it becomes a tool accessible to non-specialists and for the benefit of patients and users.

Mission : Mid infrared for a better health

DIAFIR has been established in June 2011 by an interdisciplinary team of researchers and engineers, in order to bring to  market more than 10 years of research made by Rennes 1 university.

Its mission it to promote innovative systems based upon special glasses, known as “chalcogenide glasses”.

These glasses have interesting properties for infrared light optics for instance. They can be used to make unique biosensors that allow faster and less invasive diagnostic procedures, for chronic and infectious diseases, as well as tumor detection.

DIAFIR testing offers a better care to the patient, saving him lesions and/or hospital stay generated by invasive or time consuming procedures. It helps physician to get easily a more accurate diagnosis.

Scientific Board

Jacques Lucas, Member of academy of sciences
Jacques Lucas is Emeritus professor at the university of Rennes. He founded and headed the Glass and Ceramic laboratory for many years. He supervises several research programs dealing with glasses transmitting light as far as possible in the infrared region. Among the main breakthrough is the development of optical waveguide for several applications. This includes the transmission of the energy emitted by IR laser, the development of fibers used as light filters for space applications as well as the design of IR guides for medical, biological and chemical sensors. He is a co-founder of DIAFIR. He also was a co-founder of Vertex, now Umicore IR glass.

Joel Renault, Delta Dore founder and president
Joel Renault created Delta Dore forty years ago and made it the European leader for home automation, based upon innovative ideas such as control of energy home. He is now using this outstanding experience to assist innovative start-ups in which he invests, such as DIAFIR.

Catherine Boussard, PhD, Chemistry
Research engineer at French CNRS Research institute, within glasses and ceramics team, Catherine Boussard-Plédel develops fiber from chalcogenide glass with applications in the infrared optics field. These fibers are used in devices using the evanescent-wave spectroscopy for spatial, environmental for biomedical sensors. She has been co-winner of the EADS foundation award.

Bruno Bureau, PhD, Physics
Pr Bruno Bureau has a PhD from the Université du Maine, France. He is professor at the Glasses and Ceramics laboratory at the University of Rennes 1. He is in charge of the “infrared optical sensors” group working on the creation of chalcogenide glasses for optic, the development of optical devices, including optical fibers, for bio-sensing, sea water protection, space or atmospheric CO2 monitoring. As solid state NMR expert, Bruno Bureau is also involved on more fundamental research topic related to a better comprehension of the glassy state by coupling theoretical calculations, thermomechanical and structural studies. He is the authors or co-authors of about 110 papers in the field of non oxide glasses, infrared sensing, material and glass science. He has been appointed as junior fellow to the “Institut Universitaire de France”.

Olivier Loréal, Hepato-gastroenterologist MD
Olivier Loréal, physician scientist, is research Director at UMR INSERM 991, responsible for the iron and liver team. His professional experience includes cell biology in the field of Hepatology and involvement in clinical studies. He has contributed to the development of the application of the FEWS technology to the characterization of biological samples obtained in a pathological situation.
