Italians make fastest nanomotor
Italy's has made the world's fastest nanomotor - a molecular engine designed to carry drugs into cells. Vincenzo Balzani of Bologna University is the new engines designer. The engine, called Sunny because it runs on solar power, is a million times faster than the only other eco-friendly nanomotor, recently built in the Netherlands. The Netherlands work was to anchor a chiral helical alkene onto a gold nanoparticle to create the first light-driven molecular rotary motor attached to a solid surface. (Nature 2005, 437, 1337).
