Researchers designed tiny bacteria that can be more efficient than plants at converting sunlight into useful compounds. Plants accomplish this task with the help of chlorophyll, the green pigment that helps them absorb sunlight. Scientists have designed a cyborg bacteria that can achieve the same results in a more efficient way using semiconductor nanocrystals. In order to create these crystals, researchers fed Moorella thermoacetica certain chemicals that the bacteria synthesized into cadmium sulfide nanoparticles, which function as solar panels on their surfaces. Aside from being highly efficient, the process is also self-replicating and self-regenerating, making this a zero-waste technology.
