This viscous coating is the glycocalyx that consists of several carbohydrate moieties of membrane glycolipids and glycoproteins, which serve as backbone molecules for support. Generally, the carbohydrate portion of the glycolipids found on the surface of plasma membranes helps these molecules contribute to cell–cell recognition ...
A coating is a covering that is applied to the surface of an object, or substrate. [1] The purpose of applying the coating may be decorative, functional, or both. [ 2 ] Coatings may be applied as liquids , gases or solids e.g. powder coatings .
Epicuticular wax is a waxy coating which covers the outer surface of the plant cuticle in land plants. It may form a whitish film or bloom on leaves, fruits and other plant organs. Chemically, it consists of hydrophobic organic compounds, mainly straight-chain aliphatic hydrocarbons with or without a variety of substituted functional groups ...
In general, the lower the surface tension of a liquid coating, the easier it will be to form a satisfactory wet film from it. The difference between the surface tension of a coating and the surface energy of a solid substrate to which a coating is applied affects how the liquid coating flows out over the substrate.
These coatings are usually based on organic polymers. [20] There are two classes of non-toxic anti-fouling coatings. The most common class relies on low friction and low surface energies. Low surface energies result in hydrophobic surfaces. These coatings create a smooth surface, which can prevent attachment of larger microorganisms.
In medicine, ablation is the removal of a part of biological tissue, usually by surgery.Surface ablation of the skin (dermabrasion, also called resurfacing because it induces regeneration) can be carried out by chemicals (chemoablation), by lasers (laser ablation), by freezing (cryoablation), or by electricity (fulguration).
Variable surface glycoproteins or procyclins, surface coat proteins of either the bloodstream form or the procyclic form of the parasite Trypanosoma brucei; COPI, a type of vesicle coat protein that transports proteins from the cis end of the Golgi complex back to the rough endoplasmic reticulum
Surface modification is the act of modifying the surface of a material by bringing physical, chemical or biological characteristics different from the ones originally found on the surface of a material. [1] This modification is usually made to solid materials, but it is possible to find examples of the modification to the surface of specific ...
