Harvesting energy from light using bio-inspired artificial cells

Scientists designed and connected two different artificial cells to each other to produce molecules called ATP (adenosine triphosphate). ATP is the fundamental unit that all living things use to carry and provide energy to run processes in cells. The scientists developed one group of artificial cells that generates protons when it is exposed to light. They also developed different artificial cells that contain an enzyme that can use these protons to generate ATP. The team then connected the two types of cells together.
