The SPLIT approach for enhancing the spatial resolution in pulsed STED microscopy with FastFLIM and phasor plots

Stimulated emission depletion (STED) microscopy is a powerful super-resolution microscopy technique that enables observation of macromolecular complexes and sub-cellular structures with spatial resolution well below the diffraction limit. However, resolution in the double-digit nanometer range can be obtained only using high intensity depletion laser, at the cost of increased photo-damage, which significantly limits STED applications in live...
