'Magic wand' reveals a 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

Researchers describe a revolutionary imaging technology that compresses lamp light into a nanometer-sized spot. It holds that light at the end of a silver nanowire like a Hogwarts student practicing the 'Lumos' spell, and uses it to reveal previously invisible details, including colors, in nanomaterials such as carbon nanotubes.
