Abstract

Single molecule localization microscopy (SMLM) surpasses the diffraction limit by sequentially imaging individual fluorescent molecules. By incorporating 4Pi detection to capture self-interference from the fluorescence emitters via two objective lenses, 4Pi-SMLM achieves isotropic sub 5 nm resolution in three dimensions (3D). This thesis details the design, construction, and evaluation of a Cryo-4Pi-SMLM system, aiming to enable subcellular 3D fluorescence imaging in native states with isotropic localization precision under cryogenic conditions, providing a 3D correlative light and electron microscopy solution...
