Confocal Fluorescence Microscopy

Confocal Fluorescence Microscopy

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,...

Super-resolution Fluorescence Microscopy

Super-resolution Fluorescence Microscopy

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...

Main Methods:

Implementation of a novel confocal microscope design featuring axially distributed reflecting pinholes in the detection space.
Simultaneous probing of different sample depths without mechanical axial scanning.
Configuration for two-color fluorescence imaging with a field of view exceeding one millimeter.

Main Results:

Demonstrated simultaneous multiplane imaging capability.
Achieved video-rate imaging speeds over a large field of view.
Successfully applied the technique for *in vivo* neuronal imaging in *Caenorhabditis elegans* and mouse brains.

Conclusions:

The augmented confocal microscopy technique effectively addresses the challenge of fast, large-scale volumetric imaging.
The method's versatility is confirmed through successful *in vivo* neuronal imaging applications.
This approach offers a significant advancement for high-throughput biological imaging and neuroscience research.
