Multivalent membrane binding sites on the α-synuclein oligomer result in clustering of vesicles and hemifusion of negatively charged model membranes. These multivalent, biological nanoparticles are reminiscent of inorganic nanoparticles in their interactions with membranes. Alpha-synuclein oligomers induce lipid exchange efficiently, with fewer than 10 oligomers/vesicle required to complete hemifusion. No full fusion or vesicle content mixing is observed
