Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

7.0K
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...

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

13.2K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Background:

  • Light-sheet fluorescence microscopy (LSFM) offers high-speed 3D imaging with low phototoxicity.
  • Interference light-sheet fluorescence microscopy (ILS-FM) shows promise for expanded field of view (FOV) and uniform axial resolution.

Purpose of the Study:

  • Optimize FOV and axial resolution in light-sheet fluorescence microscopes.

Main Methods:

  • Theoretical derivation and numerical simulations of LS interference effects.
  • Construction of a multi-LSFM system with interference (ILS) and non-interference (NILS) configurations.
  • Beam imaging and microsphere imaging tests to evaluate system performance.

Main Results:

  • ILS demonstrated a larger FOV compared to NILS.
  • ILS achieved more uniform axial resolution than NILS.
  • Intensity distribution profiles and microsphere imaging outcomes were analyzed.

Conclusions:

  • Modulating interference among multiple LSs optimizes intensity distribution.
