We now have a clean, cheap way of manufacturing quantum dots, an advanced, microscopic tool that scientists are learning how to use to enhance everything from solar panels to cancer treatments. All they needed was green tea leaf extract, along with a couple other chemicals.

But let’s back up, because that’s a lot to take in. Quantum dots are a kind of nanoparticle that span from two to five nanometers.

In the past, synthesizing these quantum dots was cost and waste-intensive, but a team out of Wales’ Swansea University found a way to create quantum dots from Camellia sinensis leaf extract, which is the same plant from which green and black tea are brewed. Using tea leaf extract instead of conventional ingredients meant the manufacturing process was non-toxic and cost effective. The same team also found that their quantum dots could penetrate the tiny pores on the outer membrane of skin cancer cells and stopped the growth of 80 percent of the cancerous cells in a lab sample.
