Title
Chemistry: Going for gold.
Abstract
The article cites a study which investigated that addition of gold increased conductance in miniaturized circuits. It highlights that researchers have immersed a 40-nanometre-long cadmium selenide rods in a solution containing gold. They found that this procedure capped the rod tips with gold directly and avoided the formation of a gold or a surfactant layer on the nanorod tip, both consequences of other rod-making procedures.
