Abstract:

Stimulated emission depletion (STED) microscopy has matured into a powerful and widely used super-resolution imaging method. MINFLUX which stands for minimal photon fluxes,is the next revolutionary fluorescence microscope with a spatial resolution around 1 nm in fixed and living cells. In particular, MINFLUX use a donut-shaped excitation beam whose central zero is targeted to pre-defined positions close to the fluorophore. The fluorophore position can thus be determined with a minimal number of photons and consequently within a spatio-temporal regime that exceeds alternative techniques.

 

This talk will highlight the new development of STED microscopy in our lab. We will also present the recent progress of our research group on MINFLUX imaging. Super-resolution imaging of specific synaptic proteins obtained for the first time. Moreover, quantum dots-assisted MINFLUX microscopy has great potential to investigate microstructures that require super-resolution and long-term imaging. We amply demonstrate that MINFLUX will allow researchers to address numerous biomedical and biophysical questions on the molecular scale. Based on the above results, we will outlook the role of MINFLUX in the field of artificial intelligence in the future.
