World's smallest engine smaller than ants a million times
British scientists successfully fabricated nano-sized engines with just a few billionths of meter operation by the light. According to the Telegraph, the research team at the University of Cambridge , England, engine launched the world's smallest nano-sized with a few billionths of a meter and light-based activities. Small engine size that can be used to penetrate the living cells to fight disease. The engine is called ANT (ants). "Like ants, the engine can generate bigger power than his weight. We have to face the current challenges is to control operations this nano engine, "Jeremy Baumberg, lead author of the study at the Cavendish Laboratory of Cambridge University, said. the engine prototype was fabricated from gold particles charged with super small size, mount together by type of temperature-sensitive polymers. When heated to a certain temperature with a laser beam, the motor hoarding large amounts of elastic energy, gold nanoparticles linked tightly clustered. When the engine is cooled, the gold nanoparticles quickly separated, like a spring. "The engine creates nano-Newton force 10. The force calculated on a per unit volume greater than about 10 to 100 times than any other machine, from jet engines to molecular motors, "Baumberg shared with the Washington Post. the team is in talks with private companies to commercialize new technologies in the field biology applications. "The biggest challenge today is our equipment can generate power for operators moving in one direction, a little bit like pistons in a steam engine," Baumberg said.
