Researchers recover and reuse waste gold nanoparticles
A group of US chemists has developed a straightforward method to recover and recycle gold nanoparticles from nanomaterials waste.1
The market share for gold nanoparticles is expected to increase exponentially in the next years, as they have applications in areas like medical diagnostics, storage devices and solar cells. Gold is expensive, and researchers have been developing ways to recover gold from waste. However, most methods require toxic chemicals such as mercury or cyanide.
Now, a team led by Peter Vikesland at Virginia Tech in the US has adapted a gold recovery method first developed by recent Nobel prize laureate Sir Fraser Stoddart2 to capture gold nanoparticles from waste.
