X-niff: Microcantilever-based electronic nose platform for airborne chemical vapour-sensing applications
A project team led by Prof Ramgopal Rao at IIT Bombay has been working on developing cost-effective and portable technologies for the detection of explosive compounds. The sensors, made of silicon compounds and polymers and coated with monolayers of receptor chemicals engineered to capture explosive compounds, could detect the presence of explosives at concentrations as low as only a few molecules, making them as sensitive as a sniffer dog. In principle, it consists of three main components: sensor array for response collection to targeted analyte, related electronics circuit to detect and collect the sensor response, and pattern recognition software to analyze and recognize the particular analyte based on the sensor response pattern. The developed system works in a close resemblance to the human nose hence the name.
