Succimer is an isomer of 2,3-dimercaptosuccinic acid. 2,3-dimercaptosuccinic acid is the organosulfur compound with the formula HO 2 CCH(SH)CH(SH)CO 2 H. This colorless solid contains two carboxylic acid and two thiol groups, the latter being responsible for its mildly unpleasant odour.
In photothermal cancer therapy, many gold nanoparticle molecules are used in each test and they must all be uniform in size. Including PEG coating, the nanoparticles measured to be ~130 nm in diameter. [1] Gold nanoparticles that act as drug delivery systems in conjugation with chemotherapeutic drugs typically range in size from 10 to 100 nm. [2]
Thiomalic acid is an intermediate in the synthesis of corrosion inhibitors, soil fumigants, active pharmaceutical ingredients, and electroplating agents. [ 1 ] The sodium and gold salt of thiomalic acid, sodium aurothiomalate , is used as a pharmaceutical drug for the treatment of rheumatoid arthritis .
Colloidal gold is a sol or colloidal suspension of nanoparticles of gold in a fluid, usually water. [1] The colloid is coloured usually either wine red (for spherical particles less than 100 nm) or blue-purple (for larger spherical particles or nanorods). [2]
A nanoshell, or rather a nanoshell plasmon, is a type of spherical nanoparticle consisting of a dielectric core which is covered by a thin metallic shell (usually gold). [1] These nanoshells involve a quasiparticle called a plasmon which is a collective excitation or quantum plasma oscillation where the electrons simultaneously oscillate with ...
Nanoparticles frequently agglomerate due to the high ionic strength of environmental and biological fluids, which shields the repulsion due to charges on the nanoparticles. Unfortunately, agglomeration has frequently been ignored in nanotoxicity studies, even though agglomeration would be expected to affect nanotoxicity since it changes the ...
Gold clusters, a part of cluster chemistry, is a term used to describe molecular clusters of gold or larger colloidal particles. Both types can described as nanoparticles, with diameters of less than one micrometer. [1] Gold nanoclusters have, despite intense efforts, as yet no commercial applications.
The gold nanoparticles facilitate the formation of a silver coating on the dye-labelled regions of DNA or RNA, allowing SERS to be performed. This has several potential applications: For example, Cao et al. report that gene sequences for HIV, Ebola, Hepatitis, and Bacillus Anthracis can be uniquely identified using this technique.
