Chemical sensorsNew DNA-based chemical sensor acts as an all-electronic nose
Chemical sensors are very good at detecting a single substance or a class of chemicals, even at highly rarified concentrations; biological noses, however, are vastly more versatile and capable of discriminating subtle cues that would confound their engineered counterparts; even highly trained noses, however, do leave a certain ambiguity when relaying a signal

DetectionSmart gas sensors offer better chemical detection
Smart chemical sensors can detect chemical weapon vapors or indicators of disease better than the current generation of detectors; they also consume less power, crucial for stretching battery life on the battlefield, down a mineshaft, or in isolated clinics

Chemical terrorismNaturally occurring enzyme to defend against chemical terrorism
Today, protection against nerve agents relies primarily on physical barriers such as gas masks and protective suits that can easily be breached; following exposure, people are treated with drugs that help with the symptoms but do not eliminate the nerve agent; researchers hope to change this, relying on the principles of evolution to produce a more efficient version of an enzyme that occurs naturally in all of us

Chemical detectionNew technology will allow miniaturization of chemical sensors
A new measuring technology – based on measuring near-resonant nonlinear behaviors rather than measuring chemomechanically induced shifts in linear natural frequency – will allow a dramatic miniaturization of sensors; the miniaturization will make these sensors more suitable for first response, law enforcement, and military missions
