The energy carried within the sound waves is used to basically increase the energy of these phospholipids, and that increases the kinetic energy, and so it disperses all these phospholipids. And that's exactly what allows these phospholipids to actually collectively aggregate and form the bilayer membrane and form these liposomes of interest. Now, we can also actually place specific types of molecules, molecules of interest, into the internal acreage compartment of our liposome. And the only thing that we really have to change in this procedure is instead of using a regular plane Aqueous solution, we use a solution that contains that molecule of interest. So, for instance, let's say we want to input we want to insert amino acids into this particular internal compartment. And so instead of using the aqueous solution, we would use an Aqueous solution of amino acids.
