What are the potential applications of gold nanoparticles?
Gold nanoparticles are used in resonance scattering dark-field microscopy for the detection of microbial cells and their metabolites [37], the bio-imaging of tumor cells [38], and for the detection of receptors on their surface [39], and for the study of endocytosis [40].
How does citrate affect nanoparticle synthesis?
Nanoparticles continue to aggregate until the total surface area of all particles becomes small enough to be covered by the existing citrate ions. Therefore, higher concentrations of sodium citrate result in less particle aggregation and the final size of the particles decrease.
What is the role of trisodium citrate in the synthesis of silver nanoparticles?
citrate (TSC) as a reducing agent. Silver nitrate and trisodium citrate were used as starting materials for the preparation of silver nanoparticles. The silver colloid was prepared by using chemical reduction method. 4 All solutions of reacting materials were prepared in distilled water.
What is the use of sodium citrate?
CITRIC ACID; SODIUM CITRATE (SIH trik AS id; SOE dee um SIH trayt) makes blood and urine more alkaline or less acidic. This helps prevent some kidney stones. It is also used to treat metabolic acidosis, a condition in some people with kidney problems.
What physical property of gold nanoparticle allows for single molecule detection?
Localized Surface Plasmon Resonance (LSPR)
What does citrate synthase do?
Citrate synthase catalyzes the Claisen condensation between acetyl CoA and oxaloacetate to yield, after hydrolysis of the thioester bond, citrate and CoA. This reaction probably occurs via the stabilized enolate anion of acetyl CoA.
Is trisodium citrate a reducing agent?
As per my knowledge, trisodium citrate(TSC) is best reducing agent thant monobasic citrate in Au NP synthesis. Since the ionization of TSC is quick compare to monobasic citrate in aqueous medium, further nucleation is also very fast. Hence most of Au nano particle syntheses method, TSC is used as reducing agent.
What are Nanoplates used for?
Nanoplates have applications in surface-enhanced Raman scattering (SERS), photovoltaics, molecular detection, and photothermal cancer therapies. Nanoplates are available with spectral properties optimized for green, yellow, red, and near-IR excitation.
