Nanoconjunction of DNA-retained gold nanoparticles using silver

Oligonucleotide duplexes are utilized to retain gold nanoparticles adjacently and to associate Ag + ions for the nanoconjunction of gold nanoparticles with silver. Junctions between adjoining gold nanoparticles connected by duplexes are well bridged with silver to have the crystalline structure of s...

Description
Summary:Oligonucleotide duplexes are utilized to retain gold nanoparticles adjacently and to associate Ag + ions for the nanoconjunction of gold nanoparticles with silver. Junctions between adjoining gold nanoparticles connected by duplexes are well bridged with silver to have the crystalline structure of silver. Because Ag + ions clustered around oligonucleotide duplexes are reduced on metallic surfaces, silver is produced preferably on gold surfaces near duplexes to solder gold nanoparticles with nanocontact.
