Sophisticated New Type of Chemical Sensor Created Christopher

WASHINGTON - Researchers said on Thursday they have created a sophisticated
sensor small and portable enough to be worn like a badge that could monitor
the environment for harmful chemicals, allowing people to protect against
exposure to toxic substances and spoiled foods.

The liquid crystal sensor, about the size of a small Band-Aid, could provide
real-time detection of airborne chemicals that until now have been difficult
to detect using technology that still is mostly confined to the laboratory,
according to research in the journal Science.
