New 'nanocrystal metasurfaces' can convert infrared light into the visible spectrum
Researchers realised a dull-looking 13,000-year-old weevil was actually covered in brilliant green, blue and yellow nanoscopic crystals.
As electronic transistors get tinier, they approach a point at which they won't be able to get smaller. How can we keep shrinking our devices, and making them more powerful at the same time? Light.
Nanophotonics deals with photons at the nanometre scale, and it's set to transform everything from internet speeds to turning your smartphone into a portable science lab.
