To achieve this, he extracted chloroplasts (organelles responsible for photosynthesis in plant cells) which he later encapsulated in a solution of silk proteins, which has an impressive ability to stabilize molecules.
This is the first time that an artificially created leaf has been presented with the ability to perform photosynthesis, its uses could be endless. Among others, it could be used in spaceships or it could be implemented in architectural structures, both outside and inside, to complement their ventilation systems and allow the creation of more oxygen than is consumed. These leaves use a minimum amount of water and very little light to carry out photosynthesis.
Its main motivation has been space, leaves capable of living in zero gravity and being able to make space travel.
