Liposomes are microscopic vesicles composed of one or more lipid bilayers. These spherical structures are similar in structure to cell membranes and are commonly used as carriers for delivering drugs, nutrients, or other bioactive compounds to specific targets in the body.
The structure of a liposome consists of a hydrophilic (water-attracting) outer layer and a hydrophobic (water-repelling) inner layer. This unique composition allows liposomes to encapsulate hydrophobic molecules within their interior and hydrophilic molecules within their aqueous core or on their surface.
Liposomes have been extensively studied and used in various biomedical applications, including cancer therapy, gene therapy, vaccination, and cosmetic formulations. Their versatility, stability, and ability to encapsulate a wide range of compounds make them valuable tools for drug delivery and other biomedical applications.
