^*POD/POPE/DOPE liposomes were prepared by freeze-thawing method. All the data in the table are the mean of three measurements.

^†The initial mole percentage of POD in the lipid mixture.

^‡The diameter of the liposomes based on the cumulant results of Photon Correlation Spectrometry measurements. The standard error is within 2% of the mean.

^§Polydispersity index reflecting the homogeneity of the liposomes. The standard error is within 15% of the mean.

^¶Encapsulated volume of the liposomes reported as microliter of encapsulated aqueous liposome interior per micromole of lipids. The standard error is within 7% of the mean.
