 In the 'Advanced Information' from the Nobel Committee they actually put the publications in bold which were key for the award, in the case of WE Moerner these are:

Moerner WE and Kador L (1989) Optical detection and spectroscopy of single molecules in a solid. Phys. Rev. Lett.62:2535-2538. 

Dickson RM, Cubitt AB, Tsien RY and Moerner WE (1997) On/off blinking and switching behaviour of single molecules of green fluorescent protein. Nature 388:355-358.
 

 So it is quite clear, the first detection of single molecules in a solid and the blinking behaviour of GFP, which links it quite nicely to Eric Betzig's work. In Betzig's case the early NSMO work is not in bold, but the 'Proposed Method' paper from 1995 is, putting him ahead of others in the field. Sometimes it is good to publish an idea on its own.

Anyhow, i think with the effort of the whole community including funding organisations, journal editors and countless students, this Nobel prize would not have been possible, well done everyone! Let's not forget, there were only a few microscope techniques which were worth a nobel prize before: Zsigmondi (ultramicroscope), Zernike (phase contrast), Ruska (Electronmicroscope, Binning & Rohrer (scanning tunnelling microscope).

best wishes

Andreas

I think the list will find this article entertaining:
http://www.slate.com/articles/health_and_science/science/2014/10/chemistry_nobel_prize_winners_see_microscope_images_they_made_possible_photos.html

Pay particular attention to the images.

Unrelated: I assume Betzig's award is primarily due to his demonstration of
PALM, and related follow-up work. I assume Hell's is similarly for his
demonstration of STED. What work of Moerner's are they thinking of? Is
there one specific paper/idea, like with Betzig and Hell, or is it for
decades of work on single molecules in general?
