Recently, Digital Trends profiled a Paolo di Trapani, and his work has a lot of people excited. For all the rapid progress that has been made with LEDs, no one else has made this important step towards recreating natural light.

The article explains how lighting innovations have allowed people to use artificial light in a number of amazing ways. We can change the color temperature of a light bulb with a smartphone, and we can grow food indoors, but we haven’t yet been able to mimic the way the atmosphere scatters the sun’s natural light…until now.

According to Digital Trends, di Trapani’s technology scatters the light of a panel of white LEDs with “a clear plastic panel studded with nanoparticles that are invisible to the naked eye.” What’s a nanopartical? A nanoparticle is what it sounds like: A really small particle. Nanoparticle research is currently hot because there are tons of ways that nanoparticle research could be applied in biomedical, optical, and electronic fields.
