Nature inspires first artificial molecular pump

Using nature for inspiration, scientists have developed an entirely artificial molecular pump, in which molecules pump other molecules. The machine mimics the pumping mechanism of proteins that move small molecules around living cells to metabolize and store energy from food. The pump draws its power from chemical reactions, driving molecules step-by-step from a low-energy state to a high-energy state. The pump one day might be used to power other molecular machines, such as artificial muscles, researchers say.
