WebOligonucleotides are generally conjugated to gold nanoparticles by utilizing a thiol linker chemically introduced to either the 5'- or 3'-end. Thiols have very strong affinity for gold surfaces and a thiol-modified oligonucleotide (or aptamer) can be conjugated by directly mixing the modified oligo with gold nanoparticles followed by a "salt ... WebA thiol is a compound which contains an SH functional group. The -SH group itself is called a mercapto group. A disulfide is a compound containing an -S-S- linkage. (Organic) sulfides have the structure R-S-R′, and are therefore the sulfur analogues of ethers.
WebA highly cited example was based on gold nanoparticles (AuNPs) modified with a few thiol-containing compounds including dithiothreitol (DTT), reduced glutathione (GSH), and cysteine (Cys). As ( III) was believed to crosslink these surface ligands to aggregate AuNPs and produce a red-to-blue color change. Since As ( III) can also adsorb on AuNPs ...
