Summary
Fluorescence fluctuation-based super-resolution microscopy (FF-SRM) enhances spatial resolution by analyzing temporal fluorescence signal variations. This technique offers improved imaging for live cells with relatively simple setups.
Area of Science:
- Biophysics
- Optical Microscopy
- Image Analysis
Background:
- Optical microscopy resolution is limited by light's wave nature (200-350 nm).
- Super-resolution microscopy techniques are needed to overcome these diffraction limits.
- Fluorescence fluctuation-based super-resolution microscopy (FF-SRM) offers a solution by analyzing signal variations.
Conclusions:
- FF-SRM provides a powerful approach to enhance microscopy resolution beyond the diffraction limit.
- Understanding the statistical principles behind each FF-SRM method is crucial for optimal application.
- This review offers a guide for researchers to select and implement FF-SRM techniques effectively.

7.2K
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 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,...
