DaveO Posted March 13, 2015 Share Posted March 13, 2015 If you want to make your head hurt check out this link to the 2014 Nobel Prize for Chemistry for super resolution fluorescence microscopy which broke through the Abbe diffraction limit and enabled imaging (theoretically at least) of a single molecule. Nobel prize for chemistry 2014http://www.nobelpriz...2014/press.html In an article about it in Chemistry in Australia I learnt that the light intensity required for this technique is 10 power 9 W per cm squared which makes our fluorescence pretty tame.

Andrea B. Posted March 14, 2015 Share Posted March 14, 2015 I looked at the 'popular' explanation. Quite amazing stuff. 109W/cm2 would be a lot of Blak-Rays, wouldn't it?!! Link to comment
Alaun Posted March 14, 2015 Share Posted March 14, 2015 Well, you need that power only on a few nm^2 Link to comment
