Summary
This study introduces a new method using vapor fixation and diffusion dehydration to prepare delicate fungal samples for scanning electron microscopy, preserving their structures effectively.
Area of Science:
- Mycology
- Microscopy techniques
Background:
- Scanning electron microscopy (SEM) requires sample dehydration, which can damage delicate biological structures.
- Fungal structures are particularly susceptible to distortion during traditional preparation methods.
Purpose of the Study:
- To develop a gentle preparation technique for SEM of fungi.
- To preserve the intricate morphology of fungal specimens.
Main Methods:
- Utilized vapor fixation for initial sample stabilization.
- Employed a simple vapor diffusion apparatus for dehydration.
- Applied the technique to fungi cultured on agar and natural substrates.
Main Results:
- Minimized disturbance of delicate fungal structures.
- Successfully preserved fungal morphology during SEM preparation.
- Demonstrated applicability across different growth media.
Conclusions:
- The described technique offers a reliable method for SEM preparation of fungi.
- This approach enhances the quality of ultrastructural imaging in mycology.

Fixation and Sectioning
Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Preparation of Samples for Electron Microscopy
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...
