For researchers on the cutting edge of chemistry and materials science, learning how to manipulate particles hundreds of times smaller than the diameter of a human hair and how to direct their self-assembly in a predictable way has been a formidable but exciting challenge. One of the brightest new approaches, reported in the current issue of Nature, comes from chemists Vincent Rotello and Bappaditya Samanta of the University of Massachusetts Amherst, with materials scientist Ben Yellen.
