Silk Leaf, invented by Julian Melchiorri, is the first manmade biological leaf that breathes and acts just like a real leaf. The silk material, which incorporates a suspension of chloroplasts from real plant cells, engages in photosynthesis, converting carbon dixoide, light and water into oxygen.
Melchiorri says the Silk Leaf may facilitate space travel. Plants don't grow in zero gravity, but with the Silk Leaf producing oxgyen for a spacecraft, deep-space exploration may be possible.
Here on Earth, it can be used to purify the air around us. It can absorb outside air and vent filtered air into homes and buildings.
