An illuminating possibility for stroke treatment: Nano-photosynthesis

Blocked blood vessels in the brains of stroke patients prevent oxygen-rich blood from getting to cells, causing severe damage. Plants and some microbes produce oxygen through photosynthesis. What if there was a way to make photosynthesis happen in the brains of patients? Now, researchers have done just that in cells and in mice, using blue-green algae and special nanoparticles, in a proof-of-concept demonstration.
