Abstract
Optical Nanoscopy (super-resolution) techniques such as STED and FPALM/PALM/STORM (single-molecule switching, SMS) microscopy utilize either targeted or stochastic switching of fluorescent molecules to achieve ~25 nm spatial resolution – about 10-fold below the diffraction limit. [1] The last years have seen many improvements that make these technologies suitable for a rapidly expanding range of applications.
I will report about two recent breakthroughs that significantly expand the live-cell and 3D imaging capabilities of these techniques:
I will present the scientific foundation, technical realization and application of these new techniques.
Joerg Bewersdorf has financial interest in Hamamatsu and Bruker.
