Columbia engineers build biologically powered chip

Led by Columbia Engineering professor Ken Shepard, researchers have, for the first time, harnessed the molecular machinery of living systems to power an integrated circuit from ATP, the energy currency of life. They achieved this by integrating a conventional solid-state complementary metal-oxide-semiconductor integrated circuit with an artificial lipid bilayer membrane containing ATP-powered ion pumps, opening the door to creating entirely new artificial systems that contain both biological and solid-state components. —> Read More
