Not content with fluorescing and catalysing chemical reactions, gold nanoparticles have now demonstrated that they can also improve the efficiency of DNA sequencing. This follows the discovery by a team of Chinese researchers that adding gold nanoparticles to a polymer matrix enhances its ability to separate DNA by capillary electrophoresis (CE).
Gold is proving to be a fascinating and highly adaptable material for nanotechnology researchers. Although fairly non-reactive in bulk form, gold has unveiled a raft of hitherto unsuspected properties at the nanoscale. This has led scientists to explore a wide range of potential uses for gold nanoparticles, including medical imaging and the manufacture of organic chemicals.
