An Ag + species and a capping agent are added (although the polyol itself is also often the capping agent). The Ag + species is then reduced by the polyol to colloidal nanoparticles. [ 25 ] The polyol process is highly sensitive to reaction conditions such as temperature, chemical environment, and concentration of substrates.
A capping agent is used during nanoparticle synthesis to inhibit particle growth and aggregation. The chemical blocks or reduces reactivity at the periphery of the particle—a good capping agent has a high affinity for the new nuclei. [112] Citrate ions or tannic acid function both as a reducing agent and a capping agent.
Cellulose acetate phthalate (CAP), also known as cellacefate and cellulosi acetas phthalas, is a commonly used polymer phthalate in the formulation of pharmaceuticals, such as the enteric coating of tablets or capsules and for controlled release formulations.
It can be used for root-end filling material and as pulp capping material. It has better pulpotomy outcomes than calcium hydroxide or formocresol, and may be the best known material, as of 2018 data. [1] For pulp capping, it has a success rate higher than calcium hydroxide, and indistinguishable from Biodentin. [2]
A capping enzyme (CE) is an enzyme that catalyzes the attachment of the 5' cap to messenger RNA molecules that are in the process of being synthesized in the cell nucleus during the first stages of gene expression. The addition of the cap occurs co-transcriptionally, after the growing RNA molecule contains as little as 25 nucleotides.
CAPS is the common name for 3-(Cyclohexylamino)-1-propanesulfonic acid, a chemical used as buffering agent in biochemistry. The similar substance N-cyclohexyl-2-hydroxyl-3-aminopropanesulfonic acid (CAPSO) is also used as buffering agent in biochemistry. Its useful pH range is 9.7-11.1.
