This article describes the latest advancement in nanotechnology. While it has been recognised for some time that by drawing on the mechanistic nature of some molecular interactions such as those that drive molecular motors in our bodies, this piece of work successfully demonstrates a functional nan-bot with a great purpose: cleaning carbon waste products out of water.
