HSPC:Chol (2: 1 mol%) liposomes. Relationship between particle size, measured by DLS (undiluted samples) or NTA (200× dilution), and nanoparticle concentration (A), and polydispersity and Span indices (B) as a function of the number of extrusion passages. The correlation coefficients between the particle size values measured by DLS and NTA, and PDI vs. Span values through the extrusion cycle were: r = 0.98 and 0.75, respectively. At the bottom of plot A, the number of HSPC molecules/liposome for the initial (non-extruded) and six-times extruded vesicles are given. [HSPC:Chol] = 0.125 mM.
