The vesicle elasticity measured with the extrusion method. DT vesicle formulations were extruded through polycarbonate filters with pore size of 30 nm under a constant pressure of 10 bar. The extruded volumes of these dispersions were recorded once per minute during 10 min (a). Particle sizes of the dispersions were measured by dynamic light scattering, and the elasticity indices were calculated using the extruded volumes after 5 min (b). Data shown are mean + SD of three batches.
