DESCRIPTION:Abstract:\n\nA single molecule is ridiculously tiny\, about 1 n
 anometer\, roughly 100\,000 times smaller than the diameter of a human hai
 r. Yet individual molecules rule the nanoscale activity and structure in o
 ur cells. Thirty years ago\, single molecules were first detected opticall
 y\, but how do we really detect a single molecule today\, and what good is
  it? It is an amazing fact that you can even detect single molecules with 
 your own eyes. When a new regime of science is breached\, surprises often 
 occur: single molecules show amazing dynamics\, blink on and off\, and can
  be controlled by light. Far from being only an esoteric effect\, these “s
 witching properties” of molecules can now be used to obtain “super-resolut
 ion” to see the tiny nanoscale structures inside cells. Essentially\, with
  tiny single-molecule light sources decorating a structure\, the on/off pr
 ocess is used to light up only subsets at a time\, and a pointillist recon
 struction reveals the hidden nanometer-scale structure\, opening up a new 
 frontier for understanding and applications. And if we watch single molecu
 les moving around\, we learn about details of local environments and time-
 dependent changes inside cells.\n\nBio:\n\nWilliam Esco Moerner (born June
  24\, 1953) is an American physical chemist and chemical physicist with cu
 rrent work in the biophysics and imaging of single molecules. He is credit
 ed with achieving the first optical detection and spectroscopy of a single
  molecule in condensed phases\, along with his postdoc\, Lothar Kador. Opt
 ical study of single molecules has subsequently become a widely used singl
 e-molecule experiment in chemistry\, physics and biology. In 2014\, he was
  awarded the Nobel Prize in Chemistry.\n
