STED Microscopy Breaks Optical Barrier

Researchers at the Max Planck Institute for Biophysical Chemistry in Göttingen have created a new law explaining how STED microscopy overcomes the limit proposed by Ernst Abbe in 1873 which limited the resolving power of an optical microscopes based on the wavelength of the light used. The new law which describes the resolving power of the researchers STED technique which adds a square-root element allowing theoretically unlimited optical resolution in fluorescence microscopy.
