TISSUE-BASED STANDOFF BIOSENSORS FOR DETECTING CHEMICAL OR BIOLOGICAL WARFARE AGENTS

摘要

A tissue-based, deployable, standoff air quality sensor (10) for detecting the presence of at least one chemical or biological warfare agent, includes: a cell (14) containing entrapped photosynthetic tissue, the cell adapted for analyzing photosynthetic activity of the entrapped photosynthetic tissue; means (20) for introducing an air sample into the cell and contacting the air sample with the entrapped photosynthetic tissue; a fluorometer (12) in operable relationship with the cell for measuring photosynthetic activity of the entrapped photosynthetic tissue; and transmitting means (30) for transmitting analytical data generated by the fluorometer relating to the presence of at least one chemical or biological warfare agent in the air sample, the sensor (10) adapted for deployment into a selected area.
