A new technique that uses diamonds and quantum logic to detect the tiny magnetic fields of single molecules has been unveiled by researchers in the US and Germany. The team then used the technique to detect nuclear magnetic resonance (NMR) signals from single molecules of a common protein. The researchers are now refining the method still further, and believe that it could reveal the currently unknown structures of some rare proteins……
