Fluorescence microscope is a breakthrough in research on the level of … – Market Zrdowia

As we mentioned, this year’s Nobel Prize in Chemistry received the Eric Betzig, Stefan W. Hell, and William E. Moerner for the development of a fluorescence microscope with very high resolution, which allows you to observe particles with an accuracy of one billionth of a meter. What does this mean for science?

What is fluorescence microscopy? As explained in the pages of Newsweek Assoc. Eve Műller from the Department of Biotechnology and Food Sciences at the Technical University of Lodz, it consists in introducing into the cells a substance that glows so you can see much more detail than in the case of research methods used previously.

You can see in the microscope, for example, does not only molecules but also can explore their environment, for example. concentration, viscosity, or the presence of the wall tissue of the solvent. Furthermore, the fluorescent material is not susceptible to interference. This allows for accurate observation cell, regardless of whether the cut is over, or across, and how deeply into the cell material is located – is always visible under the microscope.

This is a breakthrough in studies on a cellular level. Microscopic methods previously used did not allow to observe structures smaller than 0.2 micron. This restriction was broken – will study objects at the level of nanometers. This opens up access to other information, for example. Refraction and transmission of light at any depth of the cell.
