2006 journal article

Transcription inhibition using oligonucleotide-modified gold nanoparticles

BIOCONJUGATE CHEMISTRY, 17(5), 1178–1183.

By: C. Agbasi-Porter n, J. Ryman-Rasmussen n, S. Franzen n  & D. Feldheim n

MeSH headings : Cell Line; DNA-Directed RNA Polymerases / genetics; DNA-Directed RNA Polymerases / metabolism; Gold / chemistry; Gold / metabolism; Humans; Metal Nanoparticles / chemistry; Oligonucleotides / chemistry; Oligonucleotides / metabolism; Promoter Regions, Genetic; Transcription, Genetic; Viral Proteins / genetics; Viral Proteins / metabolism
TL;DR: The competitive binding and inhibition of T7 RNA polymerase due to specific interactions on the nanoparticle surface represents a transcription factor decoy approach in a model system and provides a basis for determining the accessibility of binding sites on nanoparticle surfaces for applications involving cell targeting or the use of nanoparticles as binding agents in solution.
