IIT-Bombay Incubated Firms Device Detects Deadly Explosives in Less Than 10 Secs #IndiaNEWS #Innovation
NanoSniffer, the world’s first microsensor-based explosive trace detector (ETD), developed by NanoSniff Technologies, an IIT-Bombay incubated startup, can detect dangerous explosives like Nitroglycerine, Ammonium Nitrate and RDX in less than 10 seconds.
Costing just one-third of the price of imported ETDs, the 100 per cent indigenously-made NanoSniffer can also identify and classify explosives into different classes of military, conventional and homemade explosives.
Once it provides trace detection of explosives weighing in nanograms (one nanogram is equal to one-millionth of a milligram), the NanoSniffer alerts security personnel with a sunlight-readable colour display attached to the device giving out visible and audible alerts.
Given the nature of threats that high-security installations like airports, railway stations, metro stations, hotels, shopping complexes, malls or places of worship face, it’s imperative that they are equipped with quality explosive detection capabilities. Launched earlier this month, the NanoSniff is looking to address its security requirements.
“The primary motivation behind the creation of the NanoSniffer was to indigenise our technology since no one has made it in India. Prior to the creation of the NanoSniffer, our startup was building miniaturised sensors for various sensing applications. Our idea was also to see how we could build a low-cost affordable device relevant to the Indian market. The MEMS (Micro-Electro-Mechanical Systems) sensor we developed could detect explosives at an affordable cost,??? Kapil Bardeja, co-founder of Vehant Technologies and director, NanoSniff Technologies, tells The Better India.

How Does The Tech Work?
In a document shared with The Better India, NanoSniff Technologies explains how it works.
“The user will swipe the surface of persons, vehicles, and bags; and therefore, will collect explosives particles on a ‘Swipe’. This Swipe will be inserted into the instrument, where the collected sample will be transferred to the microheater sensor via evaporation from the swipe. Using the principle of differential calorimetry the microheater detects whether the sample collected on the Swipe was an explosive or not,??? it states.
“When security personnel swipes a bag, they try to obtain traces of the particles which they want to detect and insert it into the analyser. Using a micro-heater, our device delivers a rapid temperature shock to the particles with everything burning at 300 degrees Celsius. If they are explosives, they exhibit different behaviour than non-explosives. So, we deliver a rapid temperature push to the traces at a nanoscale.
