This is Scientific Americans' 60-second science.

I'm Steve Merski.

Yesterday, January 24, 2018 at the World Economic Forum in Davos,

Scientific American editor-in-chief Mariette de Christina ran into Ben Faringha.

He shared the 2016 Nobel Prize for Chemistry for designing and creating molecules that function as

microscopic machines.

Ben Perringa and I are walking through Davos, about to go to our next appointment,

and I was just asking Professor Ferrega, what was exciting to him right now?

Yeah, the most exciting thing probably we're working on now is to make antibiotics that we can switch with light.

So you know antibiotics is a real big problem, eh?

Antibiotic resistance.

And what we do is we build in light switches in antibiotics and they are off and then we can switch them on with light and after 24 hours

when they have done their job they switch off automatically and the drugs don't build up resistance

that's that's what works and recently because they don't with red light and that's really

exciting because now we can get light into the body and because red bite goes very deep in the body.

And that gives us a lot of opportunities to develop these smart drugs.
