      abstract     = {By means of intramolecular folding/collapse of individual
                      polymer chains (precursors), ultra-small soft nano-objects
                      called single-chain nano-particles (SCNPs) can be
                      synthesized. Here we present a combination of scattering
                      techniques [small angle X-Ray and neutron scattering (SAXS
                      and SANS), neutron spin echo (NSE) and dynamic light
                      scattering (DLS)] to investigate the structure and dynamics
                      of SCNPs in solution and their linear precursors as
                      reference. Coarse-grained molecular dynamics (MD)
                      simulations have also been carried out to complement this
                      study. The application of SANS and SAXS has proved the
                      compaction of the macromolecules upon creation of internal
                      cross-links. However, the SCNPs obtained by different routes
                      exhibit a far from globular topology in good solvent.
                      Regarding the dynamics, we report on the first experimental
                      investigation of the dynamic structure factor of SCNPs in
                      solution. It reveals a clear impact of internal cross-links
                      through (i) a reduction of the translational diffusion
                      coefficient and (ii) an important slowing down of the
                      internal modes. The data have been analyzed in terms of
                      theoretical approximations based on the Zimm model. Both,
                      structurally and dynamically, SCNPs show striking
                      resemblances with intrinsically disordered proteins: similar
                      scaling properties reflecting sparse morphologies and an
                      extremely high internal friction.},
