A team of researchers at an Israeli university has successfully tested a technology using fluorescent bacteria and lasers that could become a safer system for detecting buried landmines.
The team at Jerusalem’s Hebrew University has tested mine detection using bacteria genetically modified to give off a fluorescent signal when mines – often made out plastic – are close, which can then be detected with a laser.
[T]he researchers say their approach relies on tiny amounts of vapor given off by the explosives in the mines.
“Our field data show that engineered biosensors may be useful in a landmine detection system,” said Prof Shimshon Belkin, who headed the experiment.
“For this to be possible, several challenges need to be overcome, such as enhancing the sensitivity and stability of the sensor bacteria, improving scanning speeds to cover large areas, and making the scanning apparatus more compact so it can be used on board a light unmanned aircraft or drone.”
