Latest Molecular switch Stories
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.
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.
