Three-dimensional total-internal reflection fluorescence nanoscopy with nanometric axial resolution by photometric localization of single molecules

Achieving high axial resolution is challenging in single-molecule localization microscopy. Here, the authors present a photometric method to decode the axial position of single molecules in a total internal reflection fluorescence microscope without hardware modification, and show nearly isotropic n...

Sumario:Achieving high axial resolution is challenging in single-molecule localization microscopy. Here, the authors present a photometric method to decode the axial position of single molecules in a total internal reflection fluorescence microscope without hardware modification, and show nearly isotropic nanometric resolution.
