Microscopy advances net Nobel Prize

Three scientists have received the 2014 Nobel Prize in Chemistry for aiding the development of super-resolved fluorescence microscopy.

For a long time, optical microscopy was held back by a presumed limitation: that it would never obtain a better resolution than half the wavelength

of light.

Working separately, this year’s Nobel Laureates in Chemistry circumvented this limitation and brought optical microscopy into the nanodimension.

Now, scientists can monitor the interplay between individual molecules inside cells, watch disease-related proteins aggregate, and track cell division at the nanolevel.

For enabling these advances, Eric Betzig, PhD, of the Howard Hughes Medical Institute in Ashburn, Virginia; Stefan W. Hell, PhD, of the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany; and William E. Moerner, PhD, of Stanford University in California, received the prize. The prize amount was SEK 8 million, to be shared equally among the Laureates.

The work in brief

In 1873, the microscopist Ernst Abbe stipulated a physical limit for the maximum resolution of traditional optical microscopy—0.2 micrometers. Drs Moerner, Hell, and Betzig were able to bypass this limit.

Dr Hell developed stimulated emission depletion (STED) microscopy. This method employs 2 laser beams. One stimulates fluorescent molecules to glow, and another cancels out all fluorescence except for that in a nanometer-sized volume.

Scanning over the sample, nanometer for nanometer, yields an image with a resolution better than Abbe’s stipulated limit.

Drs Betzig and Moerner laid the foundation for another method, single-molecule microscopy. This 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. In 2006, Dr Betzig used this method for the first time.
