Scientists are developing an alternative to the bulky plastic carbon monoxide detectors that keep homes safe. One day in the future, gas detectors that change their color to warn us of deadly fumes may be a common household supplement.
"Houseplants are omnipresent in our home environments." Neal Stewart of  The University of Tennessee co-author of the study, told the Daily Mail . "They can do much more than just sit there and look pretty, they could alert us to the dangers in our environment."
Plants already seem like a kind of air filter in many households. It has been shown that indoor plants help to filter out toxins such as formaldehyde from the air.
But researchers working on the new study believe they can do a lot more with a bit of genetic engineering. By adding more stomata ̵
You have already seen some success in the lab. Some modified plants have been able to recognize flu, mold, radon gas and other substances when they discolor or fluoresce.
While more research is needed before one of the plants is released for publication, Stewart and his colleagues have seen a future in which houses are fitted with green wall panels – the gas detectors would be most effective in dense groups, the team noted ,
"Through the tools of synthetic biology, we are able to develop houseplants Englisch: www.dlr.de/en/desktopdefault.aspx/t…_read-11374/ As an architectural design element that appeals to our senses as well as Sensors for environmental toxins that can harm our health, such as mold, radon gas, or high levels of volatile organic compounds, are used by Stewart's.
The study was published in the journal Science
