Preparation of Samples for Electron Microscopy

7.7K
To be visualized by an electron microscope, either transmission or scanning, biological samples need to be fixed (stabilized) so the electron beam does not destroy them and dried thoroughly (desiccated/dehydrated) so the vacuum does not affect them. Fixation needs to be done as quickly as possible because the sample properties will start changing as soon as it is removed from its natural environment. For example, in a tissue sample, the oxygen levels begin decreasing, causing an altered...

Imaging Biological Samples with Optical Microscopy

12.2K
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...

Overview of Electron Microscopy

16.5K
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.

    Area of Science:

    • Optical Engineering
    • Microscopy Technology

    Background:

    • Conventional microscope objectives often have fixed magnification and require mechanical adjustments for refocusing.
    • Aberration correction in optical systems is crucial for image quality but can be complex and costly.

    • To develop a continuous zoom microscope objective with dynamic aberration correction capabilities.
    • To demonstrate a digital microscope utilizing the novel zoom objective.

    Main Methods:

    • The objective integrates three electrowetting liquid lenses with two glass lenses.
    • Magnification is altered by adjusting voltages applied to the electrowetting lenses.
    • Aberrations are corrected dynamically by the liquid lenses.

    Main Results:

    • The developed objective provides continuous magnification tuning from approximately 7.8× to 13.2×.
    • The system features a fixed working distance, eliminating the need for moving parts for magnification or refocusing.
    • Dynamic optimization across a wide wavelength range is achievable.

    Conclusions:

    • The proposed electrowetting liquid lens-based zoom objective offers a compact, cost-effective solution compared to conventional systems.
    • It has potential applications in standard microscopy and advanced 3D microscopy techniques.
