Nobel Prize In Chemistry Awarded To Trio For Microscope Advancement

The 2014 Nobel Prize in Chemistry has been awarded to Eric Betzig, Stefan W. Hell, and William E. Moerner for their work in bypassing the limits of traditional optical microscopy. Hell developed a method called Simulated Emission Depletion microscopy, which uses one laser beam to cause a collection of molecules to fluoresce, and another laser beam to cancel out that fluorescence everywhere other than a nanometer-sized volume. Repeating this process over an entire sample provides nanometer resolution for the resulting image. Betzig and Moerner did important work on Single-Molecule microscopy. "The method relies upon the possibility to turn the fluorescence of individual molecules on and off. Scientists image the same area multiple times, letting just a few interspersed molecules glow each time. Superimposing these images yields a dense super-image resolved at the nanolevel." The three scientists' work was pivotal to enabling nano-scale microscopy and allowing detailed study of objects at the molecular level.

      And the second trio fitted better in chemistry than in physics.

      I think it's for two reasons: first, because the technique enables to watch molecular processes at the 'single molecule' level, and this is highly significant for chemistry, obviously.

      I think there might be a second reason too: the effectiveness of the technique depends on a lot of photochemical knowledge and proper selection of dyes, which again is another significant area of study and research in chemistry.

      Spectroscopist here (chemical physics). we're not the bad guys here! It's the biochemists fault!

      Here are the most recent "pure" chemical physics Nobel prizes: 2014, 2013 (I'd argue this is more a biochemical win than anything), 1999, 1998, 1992, 1991. Maybe you could argue fullerenes in 1996, since Kroto and Curl are pure-bred spectroscopists.

      Organic/inorganic chemistry: 2011, 2010, 2007 (sort of), 2005, 2001, 2000, 1994, 1990

      Then there's biochemistry: 2013, 2012, 2009, 2008, 2006, 2004, 2003, 2002, 1997, 1993...

      I'd say at the rate that organic chemistry develops, I think they're pretty well-represented, same with physical chemistry. Can you think of a major development in organic chemistry outside of cross-coupling and Grubbs metathesis that is Nobel prize worthy at this point? Dave MacMillian has iminium catalysis and chiral Diels-Alder, perhaps, but it's still early. After Corey's win in 1990, I can't imagine that total synthesis needs another Nobel, unfortunately. There is a lot of good developments in this field but nothing stands out to me for Nobel at the moment.

      In terms of spectroscopy, maybe the next "big" win is surface-enhanced Raman? Solid state NMR? There's the Nature paper from last year where from John Doyle at Harvard demonstrating enantiomer-specific spectroscopy using microwave spectroscopy, that could be a big deal in the next 10 years perhaps.

      Anyway, tl;dr: I'd argue biochemistry is over-represented, especially in the general literature, but that might just be me being bitter.

      [citation needed] literally.

      It's used a bit. Partly because the microscopes are really expensive. It's also only reliable on fixed cells: it can't do large areas fast and needs an immense light dose for the depletion beam, making any live cell results even more dubious than usual. I've seen the paper and video claiming 50 Hz performance. Utter crap.

      And finally, the resolution improvement is moderate. In practice on a commercial system you can maybe get 80nm on a good day with a following wind (50? yeah right!) if you have a pulse mode one.

      For fixed cells, PALM gives better results. For live cells, high density localisation techniques also give better results. OK I am biased, but I'm naturally going to do work on the techniques I think are more promising :)

      I have not seen any major breakthroughs yet where super-resolution is the enabling technology. I fully expect to because there is really cool stuff going on.

      Still, Hell no. It's fairly new and expensive, so every lab in the world is not going to have one. But it's commonplace enough that if it's used to support a result, it's not necessarily even advertised in the abstract. These results are cited by other labs as inspiration and support for their work, which in my view counts as usage. Moreover, its usage and acceptance has grown much faster than, say, the confocal microscope.

    Actually STED (stimulated emission depletion) microscopy does NOT "cancel out the fluorescence everywhere other than a nanometer-sized volume," it makes it fluoresce at another color so that you can spectrally distinguish the different areas. To do this you need two lasers, one is a focused to a regular spot (Gaussian beam) and the other has a profile that's more like a donut (see: Laguerre-Gauss beams). When you overlap these two lasers and excite the right molecules, the molecules that are in the ring formed by the donut fluoresce at one color (ie. at the same wavelength as the donut beam) and the ones that are right in the middle fluoresce at another color so with the right spectral filters you can effectively go beyond the diffraction limit with this technique.
