Liposome. Scheme of a liposome formed by phospholipids in an aqueous solution. Liposomes are composite structures made of phospholipids and may contain small amounts of other molecules. Though liposomes can vary in size from low micrometer range to tens of micrometers, unilamellar liposomes, as pictured here, are typically in the lower size ...
Unilamellar liposome. A unilamellar liposome is a spherical liposome, a vesicle, bounded by a single bilayer of an amphiphilic lipid or a mixture of such lipids, containing aqueous solution inside the chamber. Unilamellar liposomes are used to study biological systems and to mimic cell membranes, and are classified into three groups based on ...
Cationic liposomes are spherical structures that contain positively charged lipids. Cationic liposomes can vary in size between 40 nm and 500 nm, and they can either have one lipid bilayer (monolamellar) or multiple lipid bilayers (multilamellar). [1] The positive charge of the phospholipids allows cationic liposomes to form complexes with ...
A liposome extruder is a device that prepares cell membranes, exosomes and also generates nanoscale liposome formulations. [1] [2] The liposome extruder employs the track-etched membrane to filter huge particles and achieve sterile filtration. [3] [4] Schematic of a monolamellar liposome.
Artificial cell. An artificial cell, synthetic cell or minimal cell is an engineered particle that mimics one or many functions of a biological cell. Often, artificial cells are biological or polymeric membranes which enclose biologically active materials. [ 1] As such, liposomes, polymersomes, nanoparticles, microcapsules and a number of other ...
Immunoliposome therapy is a targeted drug delivery method that involves the use of liposomes (artificial lipid bilayer vesicles) coupled with monoclonal antibodies to deliver therapeutic agents to specific sites or tissues in the body. [1] The antibody modified liposomes target tissue through cell-specific antibodies with the release of drugs ...
Magyar; Македонски ... depending on the concentration of the lipid, this biophysical interaction may result in the formation of micelles, liposomes, or ...
Ligand-targeted liposome. A ligand-targeted liposome (LTL) is a nanocarrier with specific ligands attached to its surface to enhance localization for targeted drug delivery. The targeting ability of LTLs enhances cellular localization and uptake of these liposomes for therapeutic or diagnostic purposes. LTLs have the potential to enhance drug ...
