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...

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,...

Background:

Dual-objective light sheet (LS) microscopy setups and specialized chambers present complexity.
Conventional imaging chambers lack efficient illumination for advanced microscopy techniques.

Purpose of the Study:

To create a microfabrication pipeline for robust, reflective inserts adaptable to commercial imaging chambers.
To enable single-objective LS illumination, reducing complexity and retaining chamber functionality.

Main Methods:

Developed a microfabrication pipeline for inserts featuring metalized, 3D nanoprinted micromirrors.
Designed inserts with angled reflective surfaces for aligning a thin LS for cellular imaging.
Tested inserts in conventional commercial imaging chambers for mammalian cell studies.

Main Results:

Achieved over 4X improvement in signal-to-background ratio with single-objective LS illumination compared to widefield epi-illumination.
Demonstrated substantial resolution enhancement for single-molecule localization microscopy (SMLM) at the nanoscale.
Validated performance in both fixed and live cell samples.

Conclusions:

The microfabrication pipeline provides an accessible method for implementing single-objective LS microscopy.
This approach enhances imaging quality, offering benefits for diverse biological studies.
The system simplifies LS microscopy by adapting existing commercial imaging chambers.
