Genetically engineered bacteria paint microscopic masterpieces
Scientists have used genetically engineered bacteria to recreate a masterpiece at a microscopic scale. By engineering E. coli bacteria to respond to light, they've guided the bacteria like tiny drones toward patterns that depict Leonardo da Vinci's Mona Lisa. It's not artistic recognition they're after. Rather, the researchers want to show that these engineered organisms may someday be used as "microbricks" and living propellors.
"From a physicist perspective, bacteria are marvelous self-propelled micro-machines," Roberto Di Leonardo, a physics professor at the University of Rome who worked on the project, told Digital Trends. "We are studying possible ways in which these fantastic micro-robots could be controlled using physical external stimuli, such as light, in order to exploit their propulsion for transport, manipulation of microscopic systems inside miniaturized laboratories on a chip."
