MINFLUX - Nanotechnology

What is MINFLUX?

MINFLUX, or MINimal emission FLUXes, is a revolutionary optical microscopy technique that combines the benefits of single-molecule localization microscopy and stimulated emission depletion microscopy (STED). This technique allows for unprecedented spatial resolution in the nanometer range, which is a significant advancement in the field of nanotechnology.

MINFLUX utilizes a laser beam to create a donut-shaped excitation pattern. The minimal photon emission flux is located at the center of this pattern. By scanning the sample with this precise pattern and recording the emission intensities, it is possible to pinpoint the exact location of single molecules with ultra-high precision. This method reduces the number of photons required for localization, leading to faster imaging and reduced photobleaching.
