Much has evolved in recent times, smoke, heat, humidity, water pH or metal detectors, but today, there are hardly any detectors for explosives or chemical attacks.
Unfortunately, the electronic noseIn other words, a device capable of detecting molecules in the environment in a small quantity of products such as explosives, anthrax, etc., does not exist. Still in the XNUMXst century, we continue to depend on dogs for the detection of these substances.
Scientists, like the Dr. Julio Rozas of the University of Barcelona, study spiders to understand how these arachnids detect a few molecules in the air, which lead them to predictr the existence of food or the attack of predators. All this research will lead us to be able to develop electronic detection systems. This is the new panorama of chemical and biological terrorism which will be of great interest to the countries around us.
Julio Rozas says:
"In Drosophila, we are studying genes that encode proteins involved in the olfactory response to chemical stimuli, while in Arabidopsis we are studying genes that encode enzymes of the phenylpropanoid pathway."
