Abstract:

The effect of cascade amplified depletion in lanthanide upconversion systems boosts their own emission bands inhibition, which facilitates multi-color nanoscopy with only one pair of low-power NIR CW lasers.

Super-resolution Fluorescence Microscopy

8.0K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...
