abstract = {The complexation of lysozyme with aggregates from two
triblock amphiphilic polyelectrolytes of the same blocks but
different topologies and block molar masses, namely
PS-b-SCPI-b-PEO and SCPI-b-PS-b-PEO, is investigated by
scattering and spectroscopy methods. Light scattering
reveals that the interaction with lysozyme causes shrinkage
of the self-assembled nanoparticles in the case of the
hydrophobic–polyelectrolyte–hydrophilic sequence. In the
polyelectrolyte–hydrophobic–hydrophilic sequence, the
opposite trend is observed. Small angle neutron scattering
confirms the existence of micellar and fractal aggregates
and the complexation with lysozyme. The pH-dependence of the
interactions and the stability of the hybrid protein/polymer
nanoparticles upon salt addition are tested. The native
conformation of the protein is found to be preserved during
complexation. This study reveals that both micellar and
fractal aggregates made of amphiphilic triblock
polyelectrolytes are capable of loading with oppositely
charged proteins in a controllable manner, tuned primarily
by the structure of the triblock terpolymer.},
