Fabrication of silver nanoparticles ring templated by plasmid DNA
Source abstract
Abstract
Abstract Silver nanoparticles ring was successfully fabricated by electrostatic assembling 4-aminothiophenol (4-ATP) capped silver nanoparticles on predefined extended circular plasmid pBR322 DNA. The silver nanoparticles ring which was about 1.5 μm in length, and about 2.2 nm in height can be obtained by adjusting the reaction time. The normal Raman scattering spectra reveal that the 4-ATP has contacted with the silver nanoparticles by forming a strong Ag–S bond. The AFM data show that the assembly of 4-ATP capped silver nanoparticles on DNA is ordered.
