Engineers have developed a new determinant of explosives

Scientists from the University of Adelaide has created a sensor that can detect minimal amounts of explosives using light and special glass fiber.

The new sensor is able to find explosives in the lowest concentrations of 6.3 ppm. Thus the analysis requires only a few minutes. Head of development George of Diminis says: "In today's world of improvised explosive devices is not often are not metal, so we should be able to detect the very explosive". In the new sensor, the researchers used a plastic material which emits red light when illuminated with the green laser and the amount of red light decreases in the presence of explosives.

"The device has high sensitivity and we can detect tiny quantities of explosives in a small sample," says Diminish. The expert is sure that the sensor is ideal for forensic examination to determine that there was in a certain place explosives. According to the developer, the advantage of the new technology of explosives is that despite the complex physical processes at the basis of the operation of the device, it is quite simple.
