Seacoast Science's technology is based on
proprietary designs, and includes micromachined detector
arrays, readout electronics, custom synthesized polymers and
sol-gels and specialized analytical software. Thus, the
technology enables the detection and early warning of weapons
of mass destruction, toxic industrial chemicals and other
hazardous materials.

For each application, a series of polymers are chosen based on
their affinity for detecting specific chemicals. These polymers are
coated onto a sensor platform and behave like sponges to absorb
chemicals from the atmosphere. When a polymer absorbs a chemical, it
changes that polymer's ability to conduct electricity, an event that
is measured by our sensor. Seacoast Science's technology then
identifies the nature and class of chemicals being detected. Our
sensors are sensitive to most volatile organic compounds, toxic
industrial chemicals, chemical warfare agents (such as mustard and
sarin gas), and other gases.

Seacoast Science, Inc. proprietary sensors have been tested in
controlled environmental conditions. Our sensors have demonstrated
sensitivity to many Toxic Industrials Chemicals (TIC), Volatile
Organic Chemicals (VOC), Explosives, and Chemical Warfare Agents
(CWA). The sensors were capable of detecting many hazardous compounds
in air in the parts per billion range.

Specialty chemical sensing polymers, materials, and systems
Seacoast Science, Inc. has implemented its core technology in
to multiple sensor systems for custom chemical sensing applications. Our
detectors can be equipped with audible and visual detection alarms, RF
or cellular wireless transmission networks, digital displays, and air
pumps for faster chemical detection. The systems use serial
communication for easy integration.
