Gizmodo is profiling work being done at NASA Ames Research Center to develop a mobile phone powered sensor that could be used for a variety of applications from detecting chemical attacks in future military conflicts to testing blood glucose indirectly by measuring acetone in exhaled breath.
The device takes advantage of the same kind of nanosensors that are already in use on the International Space Station detecting chemicals that are effectively dangerous pollutants in the orbiting enclosed space. It works as an attachment to a smarphone (looks like an iPhone), and we are excited to hopefully one day see this technology built right into the body of the phone to provide basic diagnostic capabilities.
