Photoswitching emission with rhodamine spiroamides for super-resolution fluorescence nanoscopies

Spatial resolution in far-field fluorescence microscopy is limited by diffraction to about 200 nm. With the aid of photoswitchable fluorophores, the diffraction barrier has been successfully overcome, allowing unprecedented resolution in the order of single biomolecules. The imaging process demands...
