Exposure to inhaled mineral or metallic dust may induce interstitial lung diseases (ILDs) such as sarcoidosis or pulmonary fibrosis. These diseases are frequently considered idiopathic; however, some of them are of occupational or environmental origin. Pathologists do not investigate the nature and the origin of mineral dust exposure by lack of available and convenient technology. Since 2014, Benoit Busser is working with collaborators to develop the medical applications of laser-induced breakdown spectroscopy (LIBS), aiming at characterizing the nature of (nano)-particles in different tissue specimens. LIBS technology allows visualizing and quantifying metals and mineral dust in biological organs, and especially in the lungs. LIBS is considered as a major tool to help medical doctors in their investigations for finding origins to idiopathic lung diseases. In the context of the recent funding of our national multidisciplinary project MEDI-LIBS (ANR-17-CE18-0028), very encouraging preliminary results and the enthusiasm of our clinical partners encourage Benoit Busser (coordinator) and his collaborators to push forward and to submit a proposal for an ambitious (but realistic) European project connected to their field of expertise. They aim at creating a high-performance LIBS equipment fully dedicated to biomedical analyses. The EURO-LIBS project is innovative and relies on an international consortium of i) physicists for the construction of the LIBS instrument and training of the users), ii) clinicians for the clinical trials (expertise in pulmonology and/or occupational medicine), iii) and a “business-partner” from the Health insurance field for the economic health studies. The EURO-LIBS project, its objectives and consortium, are perfectly aligned with the scope of the next EIT Health BP 2021 call, in March 2020. The European Institute of Innovation & Technology (EIT) is an integral part of Horizon 2020, the EU’s Framework Programme for Research and Innovation.
