Description
Copper and sulfur are known for their reactivity, and in fact, it’s this reactivity that supports the development of prized flavor and aroma profiles in whisky. Motivated by this tried-and-true chemistry, researchers at the University of Strathclyde in Scotland created copper-capped microswimmers that move through fluid environments containing “whisky-inspired” sulfurous compounds.
