Synthetic Cells Act As Battery

Caption

Image of two artificial cells that can act as a tiny battery. Each cell has a droplet of a water-based solution containing a salt -- potassium and chloride ions -- enclosed within a lipid wall. If the solutions in the two cells start with different salt concentrations, then poking thin metal electrodes into the droplets creates a small electric battery.
