The multi-analyte capabilities of the device make it very attractive for applications ranging from environmental monitoring to process control. The study by Frost & Sullivan on World Gas Sensors, Detectors and Analyzers Market reveals that these markets earned revenues of over $1 billion in 2005 and estimates this to exceed $1.4 billion in 2012 (Source: Frost and Sullivan Report MC1377591, August 31, 2006). Pharmaceutical and biotechnology industries, fermentation monitoring, cell culturing, and tissue culturing represent some important applications. Upon repackaging, the device will have applications in a variety of civilian emergency response and occupational environment monitoring or related research facilities. Examples include: firefighting, hazardous material response, hazardous material workers, industrial safety workers (e.g., coal miners, steel workers, etc.), and industrial confined space monitoring associated with many occupations (e.g., industrial chemical manufacturing). NASA vision calls for safe, affordable human missions beyond Earth orbit to Mars, and through the Solar System. To support the transport of small crewed missions with capabilities to extend this to outer space, monitoring and controlling of the life-support process needs to be performed by devices having attributes such as: (a) high accuracy and precision, (b) reduced size and weight, (c) long operational life, (d) reliable performance, (e) minimal maintenance requirement, and (f) in-line operational ability. Hazardous trace gases within the space-craft crew habitat pose risks to human health during long duration missions. Therefore, the proposed sensor technology provides NASA with a low-cost, robust, real-time monitoring format for protecting both the crew and spacecraft at least for 3 years.
