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,...

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 developed.

Overview of Electron Microscopy

Overview of Electron Microscopy

The wavelengths of visible light ultimately limit the maximum theoretical resolution of images created by light microscopes. Most light microscopes can only magnify 1000X, and a few can magnify up to 1500X. Electrons, like electromagnetic radiation, can behave like waves, but with wavelengths of 0.005 nm, they produce significantly greater resolution up to 0.05 nm as compared to 500 nm for visible light. An electron microscope (EM) can create a sharp image that is magnified up to 2,000,000X.

Overview of Microscopy Techniques

Overview of Microscopy Techniques

The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

Area of Science:

Biotechnology
Digital Pathology
Microscopy

Background:

Traditional microscopy limits image sharing and analysis.
Digital pathology requires efficient methods for generating and managing large image datasets.

Purpose of the Study:

To reconfigure a standard microscope into a virtual slide generator.
To establish a system for creating, storing, and viewing high-resolution virtual slides.

Main Methods:

A robotic stage (Prior Scientific H101) and a 3CCD camera (Hitachi HV-C20) were integrated with a standard microscope.
Media Cybernetics Image Pro Plus (IP4) software controlled stage movement and image capture (640 x 480 pixels).
Images were montaged into large virtual slides, saved as TIF/JPEG, compressed to FlashPix (FPX) format, and served via MGI Zoom Server.

Main Results:

High-quality gigapixel images of tissue whole-mounts and arrays were generated using 4x, 10x, 20x, and 40x objectives.
Virtual slides were viewable via IP4 viewer, Adobe Photoshop, Kodak Imaging, and browser-based software (Neuroinformatica).
The system demonstrated efficient image generation for teaching, publication, research, and morphometric analysis.

Conclusions:

The reconfigured microscope effectively functions as a virtual slide generator.
This system facilitates the creation and dissemination of high-resolution digital pathology images.
The generated virtual slides support diverse applications in scientific research and education.
