This year’s winners of the Nobel Prize in chemistry are: Eric Betzig, Stefan W. Hell, and William E. Moerner. Distinguished them for the creation of a fluorescence microscope with very high resolution.

“For a long time optical microscopy was withheld because of the assumed limitations: such that they do not get a better resolution than half the wavelength of light. With fluorescent molecules winners of the Nobel Prize in chemistry in 2014 ingeniously got around this limitation. Their groundbreaking work has introduced optical microscopy in nanowymiar “, reads a statement of the Nobel Committee.

” With nanoskopii scientists are watching the way the individual molecules within cells. Could see how molecules formed synapses between nerve cells in the brain and can track the accumulation of proteins associated with the development of , and Huntington’s disease, track individual proteins in fertilized oocytes, which are dividing and become embryos “, explain the experts.

It seemed that in 1873 Ernst Abbe established a physical limit to the maximum resolution of conventional optical microscopy : in his opinion, could not become more accurate than 0.2 micron. Eric Betzig, Stefan W. Hell, and William E. Moerner got around this limitation and it will give you an insight into the nanoworld, explained to the members of the Nobel Committee.

“Today nanoskopia is used worldwide and is collected every day new knowledge with the greatest benefit to mankind “, said in a statement.

Eric Betzig was born in 1960 in Ann Arbor (USA). works for the Howard Hughes Medical Institute (Howard Hughes Medical Institute) in Ashburn, USA.

Stefan W. Hell was born in 1962 in Arad (Romania). works at the Max-Planck-Institut für Chemie in Göttingen biophysikalische and at the German Cancer Research Center in Heidelberg.

William E. Moerner was born in 1953 in Pleasanton, CA (USA). He is a professor at Stanford University.
