Nobel Prize in Chemistry was awarded to Eric Betzig, Stefan W. Hell and William E. Moerner for fluorescence microscopy studies. Scientists awarded for the solution of a problem, but by two different methods: Hell has developed the so-called STED-microscopy and Betzig and Moerner - single-molecule microscopy.

Method of fluorescence microscopy - painting objects with special non-toxic substances capable of light when irradiated with ultraviolet rays. This method gave better resolution than visual.

Eric Betzig Born: 1960, Ann Arbor, USA Affiliation at the time of the award: Janelia Research Campus, Howard Hughes Medical Institute, Ashburn,USA Prize motivation: "for the development of super-resolved fluorescence microscopy" Field: physical chemistry

Stefan W. Hell Born: 1962, Arad, Romania Affiliation at the time of the award: Max Planck Institute for Biophysical Chemistry, German Cancer Research Center Prize motivation: "for the development of super-resolved fluorescence microscopy "Field: physical chemistry

William E. Moerner Born: 1953 Affiliation at the time of the award: Stanford University, Stanford, CA, USA Prize motivation: "for the development of super-resolved fluorescence microscopy" Field: physical chemistry

Scientists invented and synthesized various molecules that are "attached" to the protein and when exposed to ultraviolet radiation emit visible light.

Specific molecule is attached to a specific protein in certain quantities, so that scientists can trace which molecule is involved in various processes. Active and inactive proteins have slightly different formulas that scientists can observe the activation of proteins.

Scientists with fluorescence microscopy technique and technical innovations were able to overcome the inviolable laws of nature and use it in medicine and science.
