Detecting nerve agents with the touch of a finger

There’s a reason why farmers wear protective gear when applying organophosphate pesticides. The substances are nerve agents that are very effective at getting rid of unwanted bugs, but they can also make humans sick. Even more potent, related compounds -- organophophate nerve agents -- are deadly. Now researchers have created a “lab on a glove” sensor that could check for the presence of such substances with one swipe.
