Preparation of Samples for Electron Microscopy

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...

Background:

Understanding liquid-substrate interactions is crucial for various applications.
Elastic tilting of plates in response to adsorbed liquid is a complex phenomenon.
The interplay between geometry and wetting properties requires further investigation.

Purpose of the Study:

To theoretically analyze complete wetting on a substrate with elastically tilting plates.
To investigate the feedback loop between liquid adsorption and substrate geometry modification.
To explore the potential for constructing substrates with tunable wetting and adsorption properties.

Main Methods:

Theoretical analysis of complete wetting.
Modeling of elastically tilting parallel vertical plates.
Investigation of the geometry-wetting feedback loop.

Main Results:

Adsorbed liquid induces plate tilting and clustering, modifying substrate geometry.
This geometric change alters wetting properties and subsequent liquid adsorption.
A feedback loop between geometry and wetting leads to stepped adsorption isotherms.

Conclusions:

The geometry-wetting feedback loop is a key mechanism in this system.
Stepped adsorption isotherms indicate abrupt changes in substrate geometry.
This work provides a pathway for designing substrates with tunable wetting and adsorption behaviors.
