The spontaneous self-assembled mean particle size and zeta potential of lipid–PEI compounds, as a function of the lipid-tail:PEI mole ratio. (A) As the number of conjugated lipid tails increases — the particle size increases. The polydispersity of the particles was <0.1. (B) The Zeta potential of the compounds was measured at pH 7.4 and 5.3.
