Vaporized metals serve as inks

Scientists at the Center for Nanoscale Systems have found a way to coat objects with an extremely thin layer of semiconductor that shines in vivid colors from bright pink to deep blue. This coating could replace paint in certain circumstances since it does not add any significant amount of weight and does not alter the flexibility of the substrate.
