This method provided a progress in liposome technology, since it allowed for the first time the preparation of liposomes with a high aqueous space-to-lipid ratio and a capability to entrap a large percentage of the aqueous material presented. For example, one disadvantage of sonication for liposome extrusion, is the process resulting in “limit size” vesicles, which are subject to lipid packing constraints, lipid degradation and heavy metal contamination [3]. All the methods of preparing the liposomes involve four basic stages: 1. In order to prepare GIANT VESICLES of diameter between 10 and 50um, the freeze thaw … Sign In Create Free Account. The method is based on the initial formation of a proliposome mixture containing lipid, ethanol and water, which is converted to lipsomes by a simple dilution step. Slowly pipette the lipid on the wires to make an even layer. Dispersing the lipid in aqueous media. Method of liposome preparation and drug loading Once these particles have formed, reducing the size of the particle requires energy input in the form of sonic energy (sonication) or mechanical energy (extrusion). Simple Method for the Preparation of Liposomes for … A new method for the preparation of liposomes is described that avoids the use of pharmaceutically unacceptable solvents and energy-expensive procedures such as sonication. Here, we developed two different methods to prepare liposomes and to incorporate the SMA-CytcO nanodiscs, using sonication or extrusion. Phospholipids can be from natural sources such as soya bean, egg yolk and olive oil. Analyzing the final product. The application of ultrasonic irradiation reduces vesicle size by providing energy for the lipid suspension of MLV.
