During the last decade, the team BioMolecules and Spectroscopy (BMS) has initiated a couple of new steps towards the combination of mass spectrometry and laser spectroscopy for the study of biomolecules. Several experiments have been conducted at different time scales, from femtosecond to nanosecond, and in a large range of spectral regions, from mid IR to UV and VUV. Recently, the BMS team has also extended this research field with the aim to understand the response of complex biomolecular systems under excitation, with a particular interest for specific molecular recognition and the role of a controlled chemical environment on structural modifications and radiation damages.
> Toward a characterization of the molecular origin of the indirect effects in the radiation damage
The BMS team has developed of an alternative technique to get biomolecules directly under vacuum in conditions as close as the ones encountered in solution. This method will give us the possibility to study, for the first time, these radical chemistry processes linked to indirect effects, being free from any other radiation contribution.
> Structural characterization of biomolecules
The BMS team has been involved in fruitful collaborations with other experimental groups, in order to extend our research activity to the study of model biomolecules through a combined laser-spectroscopy and mass-spectrometry approach.
