This could be used to produce circuits several orders of magnitude smaller than what is currently possible. Full story is on latimes.com." Understanding the fundamental processes of electron and ion transport and chemical reactions that occur within such films is vital to the development of new molecule-based chemical sensors, opti- cal switches, electrocatalysts, nanofabrication technology, and other electronic and photonic devices," says the Web site of Dr. Chad Mirkin, head of the team involved in this research.
