X-ray Interaction with Biomolecules in Gas Phase (XiBiGP) Workshop

The 3rd workshop on X-ray and VUV Interaction with Biomolecules in Gas Phase – XiBiGP will be organized in the frame of the 29th Summer School and International Symposium on the Physics of Ionized Gases (SPIG). The XiBiGP workshop is principally related (but not exclusively) to the Section 1 of the SPIG topics.

There has been a large interest in recent years to study biological systems (small biomolecules, amino acids, peptides, proteins etc.) by using synchrotron-based spectroscopic techniques, such as Photon electron spectroscopy (PES), Photoelectron photoion coincidence spectroscopy (PEPICO), Near-edge X-ray absorption fine structure (NEXAFS), X-ray photoelectron (XPS), X-ray emission spectroscopies etc. Particularly, gas-phase spectroscopy gives the opportunity to investigate isolated targets, under well-defined conditions. However, there has been always a challenge both to bring a large biomolecule intact into the gas phase and to obtain a high-enough sensitivity for a fine structure (and even coincidence) spectroscopy of desired species in a diluted environment. Additionally, it is even more challenging to investigate e.g. solvation effects under well-defined conditions.

The aim of the XiBiGP workshop is to present the most recent cutting-edge techniques used to investigate X-ray interaction with biomolecules in gas phase. The workshop is dominantly dedicated to young scientists, but also to all SPIG participants who might find interesting possibilities and topics regarding the multidisciplinary studies and developments of new experimental techniques. Finally, the aim of the workshop is to initiate a discussion between experts in the field on X-ray spectroscopy that could lead to further improvement of the techniques and important results.

The present 3rd XiBiGP workshop is co-organized by the Synchrotron SOLEIL (France) and will include 4 sessions related to: a) small biologically relevant molecules isolated in the gas phase (coincident spectroscopy); b) bio-functionalized nanoparticles (in vacuo aerosol spectroscopy); c) biomolecules in liquids (in vacuo liquid jet spectroscopy) and d) action spectroscopy of trapped macromolecular ions.
