Colloidal gold property
Their size and shape have a significant impact on the properties and uses of colloidal gold nanoparticles. An example of this is a rod-shaped particles, which has both transverse and longitudinal absorption peaks. The anisotropy of these particles will affect their capacity to self-assemble.
How do gold nanoparticles get used?
Drug delivery system
Gold nanoparticles can optimize the distribution of drugs to diseased cells, tissues, and organs. The delivery of drugs can be made possible by nanoparticles if distribution is insufficient. It can also target unstabilized drugs, such as siRNA and proteins. You can also deliver drugs to harder locations, like brain, retina and tumors, as well side effects that are serious, such as anticancer medicines. Nanoparticles’ properties are affected by the size of their surfaces and how they function. Their surface function and their sizes can affect the properties of nanoparticles. The variability in drug release, or the disintegration of nanoparticles (e.g. biodegradable Polymers sensitive to pH) is a reason for this. The optimal distribution of nanodrugs will make sure that the active drug can be reached at the desired time and place. Concentration must exceed min. Maximum effective concentration (MEC), must be greater than the minimum. The toxic concentration (MTC) should be lower than the effective concentration.
The use of nanoparticles containing gold is being explored for drug like Paclitaxel. Molecular packaging can deliver hydrophobic medications only. It was found that nanoparticles can bypass the reticuloendothelial cells with high efficiency.
The use of heavy metals such as gold nanoparticles to boost the dose to patients with cancer has attracted a lot attention. The fact that gold nanoparticles have the ability to absorb more tumors than normal tissue nearby makes it possible to increase doses. It is possible to increase the radiation dose by putting nanoparticles near the source. Similar to heavy ion treatment.
A method for detecting hydrogen sulfuride in the air was developed by researchers using the anti-aggregation capabilities of nanoparticles of gold. It is inexpensive and simple. The alkaline buffer solution dissolves hydrogen sulfide. It creates HSHS-, which stabilizes AuNPs while keeping them red. The solution allows you to see hydrogen Sulfide levels.
What does a gold nanoparticle consist of?
Turkevich and colleagues (1951) devised a process for creating AuNPs with a mixture of tetrachloroauric Acids (HAuCl4) as well as citric Acid in boiling hot water. Citric acid can be used as both a stabiliser and a reducer. Frances changed the ratio between citric acid (gold) in order to control the size of the particles. It is used widely to create spherical AuNPs that are moderately stable. But it can produce AuNPs larger than 100 nm.
Why are gold nanoparticles so bright red?
Resonance frequencies for gold nanoparticles fall in the visible spectrum. Red is because the smaller gold nanoparticles can be more sensitive to blue, green and yellow wavelengths.
