Concept

WETSEM® Technology is based on a proprietary capsule that is placed on the specimen stage of a standard SEM. At the heart of the capsule is a patented, nanotech-engineered transparent membrane that completely isolates a wet sample from the powerful vaccuum used in SEM chambers.

The capsule serves the combined function of specimen holder or cell culture dish, depending on the application. This unique receptacle permits electrons to enter and exit the capsule, while maintaining the sample in its natural state at atmospheric pressure.

Imaging is achieved either with backscattered (BSE) electron detection or X-ray detection, revealing high-resolution structure as well as material composition.

WETSEM® is ideally suited for fully-hydrated or liquid-containing samples – including foods, oils, cosmetics, ink, biological cells, tissues, and fluid suspensions. In certain settings, WETSEM® also enables imaging of dynamic reactions and their products.
