Ultrasound-assisted liposome preparation

Although liposomes can form spontaneously, they are rarely thermodynamically stable, so they usually require some auxiliary energy such as mechanical agitation, electric energy, US or combination of mechanical treatments. The main advantage of US assistance here is that it does not raise the temperature significantly. Ultrasonic energy has been used to assist the two most common methods of liposome preparation, namely
