      abstract     = {The conformation of single-chain nanoparticles (SCNPs) in
                      the presence of linear polystyrene crowding molecules has
                      been studied by small-angle neutron scattering under
                      contrast-matching of the crowders. A model describing the
                      scattering of aggregating polydisperse SCNPs has been
                      developed, resulting in the determination of the potentially
                      squeezed size of the individual SCNPs within aggregates,
                      their local chain statistics, and the average aggregation
                      number, as a function of crowding. Two different crowders,
                      of low and high molecular weights, are shown to have a
                      different effect: while long chains tend to impede their
                      aggregation above their overlap concentration, short ones
                      are found to mediate depletion interactions leading to
                      aggregation. Self-imposed crowding within the aggregates has
                      a similar impact on chain conformation independently of the
                      crowding of the surrounding medium. Our results are compared
                      to recent simulations and shall contribute to the
                      microscopic understanding of the phase behavior of soft
                      intrinsically disordered nano-objects and in particular the
                      effect of crowding on biomacromolecules.},
