Coarse-grained molecular dynamics simulations have been used to explore the interactions of C60 and its derivatives with lipid bilayers. Pristine C60 partitions into the bilayer core, whilst C60(OH)20 experiences a central energetic barrier to permeation across the bilayer. For intermediate levels of derivatization, e.g. C60(OH)10, this central barrier is smaller and there is an energetic well at the bilayer/water interface, thus promoting entry into cells via bilayer permeation whilst maintaining solubility in water.
