Sculpting Light to the Atom-Scale or: How Nanoscience can Enable the Intelligent Toilet
Matter can interact with light to give us superfast internet connections, or allow us to see the protein workings of our cells. But we don’t really understand the limit to this because it is only now that it is becoming possible to reliably build and assemble structures on the nanoscale that sculpt light more exquisitely.
In this talk, I will show how such nano-photonics is capable of squeezing light smaller than single molecular bonds so we can watch them directly. This opens up the use of chemistry to make springy machinery that enables colour-changing wallpapers, or its use for biosensing of molecules to tell you about your body’s health on a day-by-day basis.
