In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Dynamic metallization of spherical DNA via conformational transition into gold nanostructures with controlled sizes and shapes, published in 2021-07-15, which mentions a compound: 16961-25-4, mainly applied to gold nanostructure dynamic metalization conformational transition ionic strength; Au; Catalysis; Conformation transition; DNA template; Dynamic metallization; Surface-enhanced Raman spectroscopy, Computed Properties of AuCl4H7O3.
Despite the reversible condensation properties of DNA, DNA metalization during controlled conformational transitions has been rarely investigated. We perform dynamic metalization of spherically condensed DNA nanoparticles (DNA NPs) via a globule-to-coil transition. A pos. charged new Au3+ reagent is prepared via ligand-exchange of conventional complex Au3+ ions, which was used to synthesize spherically condensed DNA NPs simply based on the fundamental electrostatic and coordinative interactions between DNA and Au3+ ions. Interestingly, the size of the Au3+-condensed DNA NPs (Au3+-DNA NPs) and the type of reducing agents lead to the formation of different Au nanostructures with unprecedented morphologies (cracked NPs, bowl-shaped NPs, and small NPs), owing to the controlled conformational changes in the Au3+-DNA NPs during metalization. The condensed DNA NPs play significant roles for Au nanostructures as (1) the dynamic template for the synthesis, (2) the reservoir and supply of Au3+ for the growth, and (3) the surface stabilizer. The synthesized Au nanostructures are remarkably stable against high ionic strength and exhibit catalytic activities and excellent SERS properties. This is the first study on the morphol. control and concomitant dynamic metalization of spherically condensed DNA, proposing new synthetic routes for bioinorganic nanomaterials.
This literature about this compound(16961-25-4)Computed Properties of AuCl4H7O3has given us a lot of inspiration, and I hope that the research on this compound(Hydrogen tetrachloroaurate(III) trihydrate) can be further advanced. Maybe we can get more compounds in a similar way.
