Abstract:PLA-PEG composite microbubble was prepared by the double emulsion solvent evaporation method. With microbubble particle size as an index, the preparation parameters of microbubbles were optimized. Experimental results showed that the average particle size of the prepared PLA-PEG microbubbles was of 508.7 nm and Zeta potential was -30.6 mV under the conditions of PLA of 0.3 g, PEG of 0.3 g, primary ultrasonic power of 700 W, secondary ultrasonic power of 800 W, PVA of 50 mL at a concentration of 1%, and isopropanol of 5%. PLA-PEG composite microbubbles were regular round with a smooth surface. |
Key words:microbubbles; polylactic acid; polyethylene glycol |
