The damages triggered by ionizing radiation on chemical and biological targets depend on the survival probability of radicals produced in clusters of ionization-excitation events. In this paper, we report on femtolysis (FEMTOsecond radioLYSIS) of pur

We investigate the real-time probing of nonequilibrium electron transfers in aqueous solutions of disulfide molecules. Our attention is focused on the elementary steps of an IR electron transfer from a charged donor (chloride ion) to a biomolecular a

During cancer radiotherapy protocols, the early profile of energy deposition is decisive for the prediction and control of radiation-induced biomolecular and sub-cellular damage. A major challenge of spatio-temporal radiation biomedicine, a newly eme
