Super-resolved optical microscopy is a widely used tool throughout the medicine and biology community. Mostly and routinely done with organic dyes super-resolution imaging has led to various insights into cell structures and diffusional dynamics. The fundamental problem occuring with organic dyes is their rather dim brightness and their lack of photostability paired with photo-toxicity. This presentation will shed light on novel semi-conductor-based chromophores, like NV-centers in diamond, defects in hBN and CdTe quantum dots, and their use in optical nanoscale sensing schemes like StED-imaging or fluorescence correlation microscopy.
