Hairpin DNA coated gold nanoparticles as intracellular mRNA probes for the detection of tyrosinase gene expression in melanoma cells

Chem Commun (Camb). 2010 Aug 14;46(30):5557-9. doi: 10.1039/c001969k. Epub 2010 Jun 4.

Abstract

A new intracellular mRNA imaging probe has been developed that incorporates thiol-terminated hairpin oligonucleotides covalently bound to the surface of citrate-capped gold nanoparticles. The hairpin DNA-coated gold nanoparticles (hAuNPs) positively identifies tyrosinase mRNA in cultured melanoma cells.
