New material pulls carbon from the air for self-repair

The material in question is a hydrogel matrix, made of an aminopropyl methacrylamide (APMA) and glucose polymer, and an enzyme known as glucose oxidase. But the active ingredients are chloroplasts, the bits of plant cells that catalyze light during photosynthesis. In this case they were extracted from spinach leaves and embedded into the hydrogel, where they get to work plucking carbon out of the ambient air, turning it into a solid form and using that to “build” itself.
