Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and Northwestern University, Evanston, have discovered that common bacteria can turn microgears when suspended in a solution, providing insights for design of bio-inspired dynamically adaptive materials for energy.
“The gears are a million times more massive than the bacteria,” said physicist and principal investigator Igor Aronson. “The ability to harness and control the power of bacterial motions is an important requirement for further development of hybrid biomechanical systems driven by microorganisms.”
In the video swarms of bacteria turn two 380-micron long gears, opening the possibility of building hybrid biological machines at the microscopic scale.
