Scientists in Germany have developed a sensor that is able to sense oxygen and carbon dioxide at the same time.

A iridium organometallic compound is used in the construction of the sensor, according to Physorg.com.

Microscopic amounts of the compound are placed between nano-particles, which react to either carbon dioxide or oxygen molecules.

The iridium compound is responsible for sending a signal when the two gases are showing signs of reaction to the two gases.

It could also have implications for the food and drink, and biotechnology industries.

Researchers at the Institute of Analytical Chemistry, Chemo and Biosensors at the University of Regensburg are carrying out the work.

"It is likely to become a powerful tool in combinatorial microbiology, in cell-based screening for drugs, and in biomonitoring in general," Otto Wolfbeis, head of the project, told the journal Advanced Materials.

"In combination with fiber optic microsensors, in vivo sensing of oxygen and carbon dioxide should be possible."
