Analysis in the palm of your hand

We live in a dangerous world. Regrettably, these words accurately depict the current state of global affairs, as evidenced by a series of shocking acts of chemical terrorism that have taken place this year. When such terror events occur, timing of chemical information is critical. Wearable sensors have the ability to deliver such rapid, on-site analysis and provide answers for first responders to direct containment, treat victims and assist with intelligence gathering for criminal investigations.

Bringing real-time chemical analysis directly into the field has utility beyond emergency personnel. It could be used to track hazardous exposure on the battlefield, in laboratories and factories, or among the general population. So how ubiquitous will wearable chemical sensors become in our society, and how far can they take us?
