as informed in Buried landmines, which injure or kill 15,000-20,000 people each year, emit tiny quantities of explosive vapors which accumulate in the soil above them.
They enclosed the bacteria in small polymeric beads, which were then scattered across the surface of a test field in which real antipersonnel landmines were buried.
Using a laser-based scanning system, the test field was remotely scanned and the researchers were able to determine the location of the buried explosives.
The Hebrew U researchers said that the signals from the bacteria can be recorded and quantified from remote locations, making their test field, they believe, the first time landmines have been detected remotely.
Researchers at the Hebrew University of Jerusalem say they may have found a way to remotely detect unexploded landmines by using a combination of lasers and molecularly engineered bacteria that glow in proximity to the explosives.
as informed in A new system that highlights the location of landmines and unexploded ordnance using glowing bacteria could help reverse this trend.
Researchers genetically engineered bacteria to fluoresce under laser light when in the presence of explosive vapors seeping from the landmines.
“Our field data show that engineered biosensors may be useful in a landmine detection system,” says Prof. Shimshon Belkin, who genetically engineered the bacteria.
The team trialed the system on a test field in which real antipersonnel landmines were buried.
A new approach developed at the Hebrew University of Jerusalem takes a similar approach, but uses bacteria instead of plants to highlight the location of buried mines.
Hebrew University innovation: Glowing bacteria detect land mines
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.
