Gold can be used to make jewelry, but also to fight cancer. Several clinical trials are currently underway in the United States where patients are being treated with gold nanoparticles.
A basic design of a light-based chip.
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 uses photons to do amazing things.
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.
It’s just your average corner, but a far from average camera.
