With highly charged ions at low energy, molecules can be ionised on the femtosecond timescale at large distances without appreciable energy transfer. Their interaction with small amino acids leads to fragmentation by cleavage of the weakest bond similarly to other types of radiation‐induced fragmentation. A protective effect of the environment is observed when the molecules are embedded in a cluster of amino acids. The molecular cluster acts as a “buffer”, dissipating the excess energy, as described by P. Rousseau et al. on p. 930. The picture shows an artistic view of the collision between a projectile and a glycine hexamer.
