While lipid-based non-covalent catalysis cases have been presented , and some reports indicate that specific lipophiles may act as catalysts for the incorporation of new lipid monomers into vesicles , limited molecular details have been obtained on the precise mechanism and dynamics of accretion into heterogeneous lipid assemblies. This involves a challenge to investigate the influence of variegated micellar compositions by monitoring picoseconds compositional changes within nanoscopic mixed micelles, so as to be able to track the entire accretion trajectory of multiple assemblies.
