Novel cold neutron backscattering spectrometers contribute substantially to the
understanding of the diffusive dynamics of proteins in dense aqueous suspensions. Such
suspensions are fundamentally interesting for instance in terms of the so-called
macromolecular crowding, protein cluster formation, gelation, and self-assembly. Notably,
backscattering spectrometers with the highest flux can simultaneously access the center-of-
mass diffusion of the proteins and the superimposed internal molecular diffusive motions …
