Pearling of lipid vesicles induced by nanoparticles.
We show that cationic nanoparticles encapsulated within vesicles of phosphocholine lipid can induce pearling. The dynamic process occurs as two stages: formation of tubular protrusions followed by pearling instability. The breakup into individual vesicles can be controlled by nanoparticle concentration.
