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...

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,...

Imaging Biological Samples with Optical Microscopy

Imaging Biological Samples with Optical Microscopy

Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

Background:

Light sheet-based microscopy (LSBM) is crucial for high-resolution 3D biological imaging.
Miniaturized, adaptable modules are needed to enhance the accessibility and versatility of LSBM.
Existing LSBM systems can be complex and costly, limiting their widespread adoption.

Purpose of the Study:

To design and compare two novel miniaturized fibre-coupled modules for light sheet-based microscopy.
To evaluate and contrast their performance regarding image quality, chromatic aberration, and beam alignment.
To assess their suitability for imaging delicate biological structures like multicellular tumor spheroids.

Main Methods:

Development of two distinct fibre-coupled modules: one using an achromatic cylindrical lens and the other employing a spherical mirror for light sheet generation.
Comparative analysis of optical performance, including image resolution and aberration quantification.
Experimental validation using fluorescent dyes in solution and 3D multicellular tumor spheroid models.

Main Results:

Both modules demonstrated effective light sheet generation for imaging individual cell layers in 3D samples.
The achromatic lens module showed reduced chromatic aberration compared to the spherical mirror module.
Beam alignment stability and overall image quality were assessed for both systems, with specific construction details provided.

Conclusions:

The developed miniaturized modules offer a viable solution for advanced light sheet-based microscopy.
The choice between the achromatic lens and spherical mirror designs depends on specific application requirements regarding aberration tolerance and complexity.
These modules are optimized for imaging cellular layers in 3D biological samples and are adaptable to existing commercial microscopes.
