1.   And a start-up called Telenekron is working on a new class of chemical sensors for various uses in gas meters and automobiles.

2.   Chemical sensors can be deployed on the ground or in an airplane, Busbee said.

3.   Chemical sensors, a microphone and even a camera may be added, but Adkins is cautious.

4.   His new instrument works by reading volcanic gases from a distance, using a small telescope linked to a chemical sensor.

5.   One of the latest possible uses for nanotubes is as tiny chemical sensors.

6.   The electronic tongue uses chemical sensors that could soon be used to monitor the quality of bottled mineral water.

7.   The nose is a three-pound box full of chemical sensors connected to a small, palmtop computer.

8.   The team attached four well-known chemical sensors to minute beads made of polyethylene glycol and polystyrene.

9.   Working on the minirobot was something of a departure for Adkins, who usually develops hand-held chemical sensors.

10.   Chemical sensors sample air outside factories suspected of making chemical weapons.
