When will artificial molecular machines start working for us? Physicist Richard Feynman in his famous 1959 talk, "Plenty of Room at the Bottom," described the precise control at the atomic level promised by molecular machines of the future. More than 50 years later, synthetic molecular switches are a dime a dozen, but synthetically designed molecular machines are few and far between. Northwestern University chemists recently teamed up with a University of Maine physicist to explore the...

Our cells are controlled by billions of molecular "switches" and chemists at UC Santa Barbara have developed a theory that explains how these molecules work. Their findings may significantly help efforts to build biologically based sensors for the detection of chemicals ranging from drugs to explosives to disease markers.Their research is described in an article published this week in the Proceedings of the National Academy of Sciences (PNAS).Biosensors are artificial molecular switches that...
