“for the development of
super-resolved fluorescence microscopy”
--> The Royal Swedish Academy of
Sciences announced on Wednesday that 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.
--> Helped by fluorescent molecules, the
Nobel laureates in Chemistry 2014 ingeniously circumvented this limitation.
Their ground-breaking work has brought optical microscopy into the nano
dimension.
--> In what has become known as
nanoscopy, scientists visualize the pathways of individual molecules inside
living cells. They can see how molecules create synapses between nerve cells in
the brain; they can track proteins involved in Parkinson's, Alzheimer's and
Huntington's diseases as they aggregate; they follow individual proteins in
fertilized eggs as these divide into embryos.
--> It was all but obvious that
scientists should ever be able to study living cells in the tiniest molecular
detail. In 1873, the microscopist Ernst Abbe stipulated a physical limit for
the maximum resolution of traditional optical microscopy: it could never become
better than 0.2 micrometres.
--> Americans Betzig and Moerner and
German scientist Hell have been awarded the Nobel prize in chemistry 2014 for
having bypassed this limit. Due to their achievements the optical microscope
can now peer into the nanoworld. Two separate principles are rewarded.
