A liposome, an artificial vesicle comprises a double layer of fatty acids. It may be used as tools utilized to administer nutrients and pharmaceutical drugs to your body systems. They may be made by disrupting some biological membranes which may somehow involve sonication.
Liposomes are typically made of natural phospholipids. Besides, they may also be made of a combination of lipid chains bearing somewhat a high degree of surfactant features. These lipid chains might contain egg phosphatidylethanolamine. Their model may take the shape of surface ligands which are used for linking the tissues which are unhealthy.
There are quite different categories of these synthetic lipid laden vesicles. The major types of liposomes are multilamellar vesicle that is shortened as MLV, small unilamellar vesicle that is abbreviated as SUV, large one lamellar vesicle whose short form is LUV, and lastly the cochleate vesicle. This depends on their number of lamella.
These products can easily be confused with micelles and reverse micelles. This might occur because they are nearly similar in structure. Their only difference is that liposomes have a double layer of lipids whereas micelles as well as reverse micelles are made of single layers of lipids.
The membrane of the structure comprises of phospholipids that alludes to the molecules having tail groups and head groups. Their heads get attracted to water. However, the tail is made of only a long chain of hydrocarbons hence usually get repelled by water.
The hydrophilic heads do form the outer layer while the hydrophobic tails form the inner layer. This is because the heads are attracted by water while the tails are repelled by water. However, in each cell, one layer of heads does face outside, attracted to the surrounding water. The other layer of heads on the other hand faces inside cell, attracted to the water that is found inside the cell. However, the hydrophobic tails of the outer layer face the hydrophobic tails of the inner layer, thus forming a bilayer structure.
Liposomes were made first by a British hematologist, Dr. Alec Bangham, 1961 in the Babraham Institute at Cambridge. However, its publication took place later in 1964. They were simply found to bear a resemblance to plasmalemmas. This was demonstrated by pictures which were formed by the microscope which Bangham had used.
They encapsulate an aqueous solution using a hydrophobic membrane. Chemicals which are insoluble in water easily pass across their membranes whereas the ones soluble in water do not. Nonetheless, dissolved hydrophilic particles are able to go through hydrophilic heads. As a result, it may be utilized in releasing hydrophobic and hydrophilic particles. It releases its constituents by adhering to other organelles with similar bilayer walls for instance cell membranes.
These vesicles are utilized in drug and gene delivery services. The drugs and DNA to be conveyed usually contain pH that is appropriate for the roles of any liposome. Its application in DNA transformation is referred to as lipofection. Besides, it can as well be used in delivering dyes to textiles, pesticides to plants, enzymes and nutritional boosters to foods as well as and also cosmetics to skin.
