Abstract (AI)
In 1873, Ernst Abbe discovered what was to become a well-known paradigm: the inability of a lens-based optical microscope to discern details that are closer together than half of the wavelength of light. However, for its most popular imaging mode, fluorescence microscopy, the diffraction barrier is crumbling. Here, I discuss the physical concepts that have pushed fluorescence microscopy to the nanoscale, once the prerogative of electron and scanning probe microscopes. Initial applications indicate that emergent far-field optical nanoscopy will have a strong impact in the life sciences and in other areas benefiting from nanoscale visualization.
Key Findings
1
Early applications show that far-field optical nanoscopy will strongly impact life sciences and other fields needing nanoscale visualization.
2
Ernst Abbe's diffraction limit (≈ half the wavelength) traditionally constrained lens-based optical microscopes.
3
Far-field optical nanoscopy achieves nanoscale imaging previously limited to electron and scanning probe microscopes.
4
Fluorescence microscopy has developed physical concepts that overcome the diffraction barrier, enabling nanoscale resolution in the far field.
