Using the ultrasonication and agitation method of liposome preparation, what concentration of lipid is necessary to prepare lipo
Galina-37 [17]

The concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

<h3>What are liposomes?</h3>

Liposomes are vesicles which are made up of a lipid bilayer membrane.

Liposomes are important as delivery vehicles for substances such as drugs.

Ultrasonication is a method of liposomes preparation.

Solution of liposomes is dependent on the size.

The larger the diameter, the smaller the l elution volume. Also, increasing lipid concentration will decreases elution volume.

Therefore, the concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.
