What is a capping agent in nano chemistry?

Capping agents such as trisodium citrate are used to stop growth of nanoparticles and stabilise them from aggregation. Its effects are generally short lived though, it has been reported though that using trisodium citrate with the lee and miesel method can lead to particles that are stable for up to a month.


What are the common capping agents?

Common capping agents include thiols, amines, and carboxylic acids, which are often used to stabilize nanoparticles during synthesis. These agents help control particle growth and prevent agglomeration by binding to the surface of the nanoparticles. Additionally, polymeric capping agents like polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) are frequently employed for their ability to provide steric stabilization. The choice of capping agent can significantly influence the properties and reactivity of the resulting nanoparticles.

Mechanism of end capping in hplc column?

A column is said to be endcapped when a small silylating agent, such as trimethylchlorosilane, is used to bond residual silanol groups (-OH) on a packing surface. It is most often used with reversed-phase packings and may cut down on undesirable adsorption of basic or ionic compounds.
