Nanoparticle reveals sulfur's Midas touch

Abstract:
Researchers in the US have taken a snapshot of the inside of a gold nanoparticle, shedding crucial new light on one of chemistry's longest-standing questions: how does sulfur bind to gold?1

For centuries it has been known that gold, one of the most inert of metals, will react with sulfur and that sulfur-containing compounds will bind to gold. Theories abound about how this can occur but to date there has been little solid evidence to support any of them.

Now a team led by Robert Kornberg from Stanford University in California has solved the atomic structure of gold nanoparticles coated with the sulfur-containing compound p-mercaptobenzoic acid, revealing the nature of the bond in unprecedented detail.
