It’s amazing when we see stories about science-fiction becoming a reality. Pictured above is a clip-on nanosensor for a mobile phone that has been developed by NASA to detect toxins in the air, alerting you when it senses harmful substances.
First developed for use around launch sites to detect fuel leaks, and on the International Space Station to detect possible leaks of harmful gases, the sensor is now being developed as an addition to a mobile phone. Pictures of the sensor suggest it’s for an iPhone, but surely it’s capable of working with most modern handsets. It has many use cases, but one of the most promising is helping to detect diabetes or even cancer in individuals.
