Understanding the solvation effects of water in biologically relevant molecules promises to unravel elementary steps in elementary biophysical reactions. The effect of single water molecules on various naturally occuring biologically relevant molecules was successfully investigated before, even fully resolving all reactants and products [1]. We propose to push the frontiers of such highly controlled and specific chemical-dynamics eperiments by investigating the effects of multiple water molecules on different prototypical biomolecules, e.g., DNA bases. The ultrafast solvation-dynamics will be investigated with femtosecond temporal resolution using strong-field ionization probes and multi-mass velocity-map imaging with Timepix3 detectors [2]. In the future, complexer systems will be investigated at photon research facilities such as EuXFEL, FLASH, PETRA III, or MAX IV.
