Scientists have created a way to detect buried landmines using glowing bacteria and lasers in a breakthrough that could lead to a safe method for the disposal of the devices.
Using the glowing bacteria method, such teams could map where landmines are likely to be buried and then target their disposal attempts more securely.
There are an estimated 110 million armed mines buried across the world that are responsible for up to 20,000 injuries and fatalities a year.
Bomb disposal teams often have to carefully hunt for minefields on the ground, risking their lives in order to find where the mines are buried.
Despite the scale of the problem, which affects some 70 countries, the methods used to detect and dispose of landmines have remained largely unchanged since the Second World War.
as informed in Fluorescent bacteria enclosed in polymeric beads illuminated by a laser-based scanning system have been used by Hebrew University of Jerusalem researchers to remotely detect buried land mines.
The need for safe and efficient technologies to detect unexploded ordnance is a humanitarian issue of huge global proportions.
Please share on Linked in The major technical challenge in clearing minefields is detecting the mines.
The technologies used today are not much different from those used in World War II – detection teams endanger their lives by entering the minefields.Prof.
More than 100 million such devices are buried in more than 70 countries.
as informed in Glowing bacteria detect buried landmines More than 100 million landmines lay hidden in the ground around the world, but glowing bacteria may help us find them, according to a new study.
The bacteria will also need to be optimized to find mines buried in rougher terrain, or ones that use explosives besides TNT.
Twenty-four hours later, they used a laser to remotely detect and quantify fluorescing bacteria from 20 meters away, mapping the location of the landmines.
In a study published in Nature Biotechnology today, the same team reports on a small field test with mines buried in sand and soil, whose triggering mechanisms were removed.
The approach relies on small quantities of vapor released from the common explosive TNT.
