A prototype device able to identify toxic airborne chemicals in seconds could monitor air quality in real-time to detect gas leaks and pollution.
The sensor was developed by a team from Nanyang Technological University using a chip made of a porous metal-organic framework nanomaterial that traps nearby gas particles. A laser shone onto the chip will interact with the gas molecules to produce a lower-energy form of light, which can be analyzed by a camera to identify its spectroscopic signature for comparison to known toxic gases. The process takes only about 10 seconds to complete, rather than the several days required in some instances.
