Distribution of particle size (a) and ζ-potential (b) of the prepared CpG ODN-loaded DOTAP/DC-chol liposomes with various N/P ratios. The particle size and ζ-potential of the prepared CpG ODN-loaded DOTAP/DC-chol liposomes were measured by NICOMP 380 ZLS. The particle size and ζ-potential are expressed as the mean ± standard error for samples assayed in triplicate
