New technology: Mine detection with 'bacteria' sensor

Israeli researchers introduced a new mine detection system that uses a combination of lasers and bacteria to remotely detect the location of unexploded, unexploded antipersonnel mines.

The design of the Hebrew University in Jerusalem is based on the observation that all mines emit a small amount of explosive gas, which accumulates in the soil above the mine, thereby marking the presence of mines.

According to a report in the journal Nature Biotechnology, researchers created live bacteria that emit a fluorescent (glowing) signal when exposed to explosive gases. This signal can be recorded and remotely located the location of an underground mine.

Bacteria (used as biosensors) are packed in small packages and strips on the ground in the area to be examined, where hidden real mines remain hidden. Using this laser scanning system, remote monitoring can be done to determine the location of mines.

" Our empirical data demonstrates that these generated biosensors can be usefully used in this mine detection system. To complete this system, there are still many challenges to overcome, For example: improving the sensitivity and stability of bacteria - sensors, improving the scanning speed to be able to detect larger areas, the scanner should be more robust to be placed on the machine compartment. flying or mounted on a light unmanned aircraft " , Professor Shimshon Belkin of the Alexander Silberman Institute, Hebrew University in Jerusalem, is in charge of the genetic-sensor genetic engineering said.

Humanitarian issues are on a large scale

The need for safe and effective technology to detect unexploded, unexploded mines is a global humanitarian issue, to a great extent.

About half a million people around the world are affected by anti-personnel mines, in addition, every year 15 to 20,000 people are injured or killed by trampling on landmines, more than 100 million mines of all kinds are still buried. in more than 70 countries.

The biggest technical challenge to clear areas with mines is to discover these mines. Technologies used today are not much different from those used during World War II, still need mine detection teams. And this way of doing so exists the risk of death or injury when employees go into the minefield to detect quite high.
