Optical Nanoscopy
Dr. Andreas Schönle, Department of NanoBiophotonics, Max-Planck-Institute for Biophysical Chemistry, Göttingen

In 1873, Ernst Abbe discovered that diffraction limits the resolution of a lens-based optical microscope to half the wavelength of the light in use. Other imaging modalities like electron- or atomic-force microscopy feature nanoscale resolution but could never replace far-field fluorescence microscopy due to their limited applicability especially in the life sciences. Non-invasive, specific imaging on the sub-micron scale was therefore considered impossible for more than a century. But recently, new concepts emerged that achieve resolutions far beyond the postulated limit, while still using visible light and far-field focusing. I will introduce these concepts and discuss the underlying physical principles that allow them to annul the diffraction barrier.
