“Magic Wand” Reveals a Previously Invisible Colorful Nano-World

Novel color photography using a high-efficiency probe can super-focus white light into a 6-nanometer spot for nanoscale color imaging. Scientists have developed new materials for next-generation electronics so tiny that they are not only indistinguishable when closely packed, but they also don’t reflect enough light to show fine details, such as colors, with even the most powerful optical microscopes
