From this day onwards a cellphone no longer makes only calls, it can now smell gas too. Yes, seriously. Jing Li, a NASA scientist has “developed a proof of concept of new technology that would bring compact, low-cost, low-power, high-speed nanosensor-based chemical sensing capabilities to cell phones.” The sensor attached to the iPhone can detect minimal concentrations of chlorine gas, ammonia and methane. The values are then shown in an app. So I guess it’s true about the iPhone…there “is” an app for almost everything!

Jokes apart…the sensor consists of silicon-based chip integrated in a micro-board consisting of 64 nanosensors. Pretty cool indeed!
