Scientific summary

The researches of FemtoChemicalBiology Group at LOA (Ecole Polytechnique - ENSTA, Palaiseau) are developed at the interface of fundamental physical chemistry and biomedical sciences, using ultrashort laser facilities and high-time resolved spectroscopic techniques. They concern the innovating domain of Bioradical Femtochemistry for which photo and radio-induced radical events can be investigated at the time scale of small molecular motions, typically in the temporal range 10-13 – 10-11 s.  At the international level, femtochemistry has been honoured in 1999 by the Nobel Prize in Chemistry, awarded to Prof. Ahmed Zewail (Caltech University, USA). More recently (2018), Ultrafast laser science has  been honoured by the Nobel Prize in Physics, awarded to Prof. Gérard Mourou (former director of LOA, Ecole polytechnique-ENSTA, France).

  • ·  Research developments - Innovating approaches

Since 2003  Implementation and development of High Energy Radiation Femtochemistry (HERF), using TW-laser plasma accelerator and ultra-short particles bunches in the MeV domain. Investigation of prethermal bioradical processes in condensed phase. Transdisciplinary developpement of advanced spatio-temporal radiation biomedicine: new concepts for real-time nanodosimetry, time dependent molecular EBR for normal and cancerous cells, pulsed cancer radiotherapies at high dose rate (NANOBIODOS project supported by AVIESAN and INCa, 2012-2015).

Spatio-temporal radiation biophysics represents a newly emerging interdisciplinary research field driven nowadays in strong synergy with the most recent progresses of molecular biology, genomics and proteomics, biomarker detections, X-ray synchrotron micro-imaging, well-defined spatial irradiation with microbeams, pulsed relativistic particle sources delivered by TW laser-plasma accelerators, selective targeting radiopharmaceutical, advanced radiation therapies of cancers. https://link.springer.com/chapter/10.1007/978-3-319-31563-8_2

MELUSYN network organizes regularly thematic days and transdisciplinary joint meetings. In 2009 it has initiated the organization of an international ESF-EMBO conference entitled “Spatio-Temporal Radiation Biology: Transdisciplinary Advances for Biomedical Applications”. http://archives.esf.org/scientific-support/conferences/conf-list-archives.html?year=2009 

A Special Issue devoted to this emerging domain has been published in Mutation Research Reviews (Y.A. Gauduel Ed, 212 pages, 2010) http://sciencedirect.com/science/journal/13835742/704

Previous researches

1984 - 2002 Development of low energy radiation femtochemistry (LERF) in the UV-IR domain and pioneering works on ultrafast dynamics of excited electron and bioradical processes in liquid water, ionic solutions, organized assemblies and biomimetic systems.

1976 – 1984  Biophysical aspects of molecular oxygen activation and oxidative stress during myocardium post-ischemia. Molecular regulation of bioradical and energetic pathways in cardiac tissue.

  • ·  Research valorisation

1984 -1992, collaboration with a cardiac surgery team (Lariboisière hospital, France) for the elaboration of a cardiac transplant preservation process (Cardioplegic Celsior solution). This process has been validated by the Food and Drug Administration (USA) in 1999 and is actually distributed by IGL Group all over the world http://groupe-igl.com/
