University of Cambridge researchers used 3D printing to create lattices of high-rise “nano-enclosures” in which sun-loving bacteria can grow rapidly. Researchers were then able to extract the bacteria’s waste electrons left over from photosynthesis, which could be used to power small electronic devices.
