A Nano-nose to Compete with a Dog’s

Nanotech-inspired Sensor “Sniffs Out” Explosives. Nano-sized Chip “Sniffs Out” Explosives Far Better than Trained Dogs: TAU researcher’s groundbreaking sensor detects miniscule concentrations of hazardous materials in the air

Security forces worldwide rely on sophisticated equipment, trained personnel, and detection dogs to safeguard airports and other public areas against terrorist attacks. A revolutionary new electronic chip with nano-sized chemical sensors is about to make their job much easier.

The groundbreaking nanotechnology-inspired sensor, devised by Prof. Fernando Patolsky of Tel Aviv University’s School of Chemistry and Center for Nanoscience and Nanotechnology, and developed by the Herzliya company Tracense, picks up the scent of explosives molecules better than a detection dog’s nose. Research on the sensor was recently published in the journal Nature Communications.

Existing explosives sensors are expensive, bulky and require expert interpretation of the findings. In contrast, the new sensor is mobile, inexpensive, and identifies in real time–and with great accuracy–explosives in the air at concentrations as low as a few molecules per 1,000 trillion.
