The Groundbreaking Science Discovery Few People Have Ever Heard Of

40 years ago, a technique now used for detecting tiny quantities of molecules, in situations from crime scene forensic analysis, to drug detection, to establishing the origins of works of art, was discovered.But despite there being a dozen CSI shows that use this on American television, you probably never heard of it. In the early 1970s, researchers discovered that by roughening the metal surface upon which the molecules they were examining had been placed, they could increase the signal by which they could detect these molecules - by a million times. It became arguably the most sensitive method of analysis on surfaces that anyone has ever come up with. read more
