Nanoporous sensors: a unique technology

ETHERA's technology is the result of nearly 10 years of research in a CEA/CNRS laboratory.

It is protected by several patents, and is based on ETHERA's unique experience in nanoporous materials engineering.

Formaldehyde nanoporous sensors
after different levels of exposure

The materials are produced using an established Sol-Gel process. Their porosity results in a very important surface area, allowing them to trap large quantities of the targeted gases. Thanks to specific colorimetric reagents, the detection of the pollutants is made possible, based on the color variation of these initially transparent materials. The reading can be performed visually or with an optical reader for more accurate results. 


This technology allows for highly sensitive and selective sensors. Incorporated in our measuring kits, it detects and quantifies with great precision the concentration of chemical pollutants, particularly volatile organic compounds (formaldehyde, BTEX, aldehydes, etc.)
