      abstract     = {We present a small-angle neutron scattering (SANS) and
                      neutron spin echo investigation on the structure and
                      dynamics of irreversible single-chain nanoparticles (SCNPs)
                      in dilute solution. SCNPs are ultra-small soft nano-objects
                      obtained by intramolecular folding/collapse of individual
                      linear polymer chains (precursors). SANS has demonstrated
                      the compaction of macromolecules upon creation of internal
                      cross-links, although their conformation is far from a
                      globular topology. To describe the dynamic structure factor
                      of the SCNPs in solution, we have taken into account their
                      dual polymer/nanoparticle character and applied theoretical
                      approximations based on the Zimm model. The study reveals
                      relaxation of internal degrees of freedom but clearly slowed
                      down with respect to the precursor counterparts. This effect
                      is attributed to the internal friction associated to the
                      compartmentation in domains within the macromolecule. We
                      discuss the structural and dynamical similarities of SCNPs
                      with disordered proteins, in particular with intrinsically
                      disordered proteins. The high internal friction in both
                      cases seems to be associated to the existence of internal
                      domains.},
