One of the main problems of the use of space by man is the generalized lack of oxygen in the universe. Here on Earth, trees and other plants perform considerable work to recycle the carbon dioxide, exhaled by us, and create oxygen for us.
So why not take these biological oxigen factories in space, but without all of these things as soil, sun, water and gravity, without which they can not exist?\
Guided by this idea, a graduate of the Royal College of Art Julian Melchiorri created the first synthetic and biologically functional leaf that absorbs carbon dioxide, water and light and produces oxygen. The leaf consists of chloroplasts encased in silk proteins. „This material has a startling capacity to stabilize chloroplast organelles,“ said Melchiorri. „As a result, I received my first photosynthetic material that lives and breathes like a leaf.“
