Table 1 Particle sizes and zeta potentials of the lipid-stabilized contrast agents
Figure 2 Average diameter (A), diameter distribution (B), and percentage of small droplets (C) of lipid-stabilized droplets and the control after ultrasonic nebulization. In B, the blue columns represent the volume frequency percentage and the red curve represents the cumulative volume percentage; in the cumulative volume overlay graph, pink indicates L1, black indicates L2, green indicates L3, blue indicates L4 and red indicates the control.
