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 ...
Lipid bilayer. This fluid lipid bilayer cross section is made up entirely of phosphatidylcholine. The three main structures phospholipids form in solution; the liposome (a closed bilayer), the micelle and the bilayer. The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules.
The earliest model bilayer system developed was the “painted” bilayer, also known as a “black lipid membrane.” The term “painted” refers to the process by which these bilayers are made. First, a small aperture is created in a thin layer of a hydrophobic material such as Teflon. Typically the diameter of this hole is a few tens of ...
A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. [1] The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating ...
Vesicle (biology and chemistry) Scheme of a liposome formed by phospholipids in an aqueous solution. In cell biology, a vesicle is a structure within or outside a cell, consisting of liquid or cytoplasm enclosed by a lipid bilayer. Vesicles form naturally during the processes of secretion (exocytosis), uptake (endocytosis), and the transport of ...
The Journal of Liposome Research is a peer-reviewed academic journal that publishes original research on the topics of liposomes and related systems, lipid-based delivery systems, lipid biology, and both synthetic and physical lipid chemistry. The journal also publishes special issues focusing on particular topics and themes within the general ...
The major sphingoid base of mammals is commonly referred to as sphingosine. Ceramides (N-acyl-sphingoid bases) are a major subclass of sphingoid base derivatives with an amide -linked fatty acid. The fatty acids are typically saturated or mono-unsaturated with chain lengths from 16 to 26 carbon atoms. [ 25 ]: 421–2.
Stranski–Krastanov growth. Stranski–Krastanov growth (SK growth, also Stransky–Krastanov or ' Stranski–Krastanow') is one of the three primary modes by which thin films grow epitaxially at a crystal surface or interface. Also known as 'layer-plus-island growth', the SK mode follows a two step process: initially, complete films of ...
