Spinach nanoparticles help failing rat hearts via 'borrowed photosynthesis'
A spinach leaf can turn light into chemical energy. A struggling heart cannot.
Summary
A spinach leaf can turn light into chemical energy. A struggling heart cannot. Researchers in China have brought part of the leaf's energy-making machinery into rat heart cells to test whether borrowed photosynthesis could help an overworked heart. Their spinach-derived nanoparticles, when combined with red light, improved pumping function and reduced tissue damage in rats with experimentally induced heart failure.
