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.

What is alkylating agents?
An alkylating agent is a compound that's capable to replace a hydrogen for an alkyl group to a specific place on a molecule. Alkylating agents attacks mostly on a nitrogen, oxygen or sulfur. Common alkylating agents are: Methyl iodide(or other haloalkanes), dimethylsulfate and some carboxylic acid alkyl esters.
What are the dehydrating agents?
Dehydrating agents are substances that remove water from other compounds or mixtures, typically facilitating chemical reactions or preserving materials. Common dehydrating agents include sulfuric acid, phosphorus pentoxide, and anhydrous magnesium sulfate. These agents are often used in laboratories for drying solvents or in organic synthesis to drive reactions to completion by removing water. Additionally, they can serve as desiccants in various industrial applications.

Cyanide
What is microbistatic agents?
Microbistatic agents are substances that inhibit the growth and reproduction of microorganisms without necessarily killing them. These agents work by interfering with essential cellular processes, such as protein synthesis or cell wall formation, effectively slowing down microbial proliferation. Common examples include antibiotics like tetracycline and certain disinfectants. Their use is crucial in controlling infections and preserving the effectiveness of antimicrobial treatments.
What are Hematopoietic agents?
Hematopoietic agents are substances that stimulate the production of blood cells, primarily in the bone marrow. These agents are often used in medical treatments to manage conditions like anemia, neutropenia, and thrombocytopenia, which can arise from various causes, including chemotherapy, bone marrow disorders, or chronic diseases. Common examples include erythropoiesis-stimulating agents (ESAs) for red blood cell production and granulocyte colony-stimulating factors (G-CSF) for white blood cell production. By enhancing blood cell production, these agents help improve patient outcomes and reduce the risk of complications associated with low blood cell counts.

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.
