This Phase I SBIR project will demonstrate the feasibility of a novel method for monitoring volatile organic compounds (VOCs) such as ubiquitous hazardous solvents in military or industrial environments and their neighboring communities. The long-termobjective of the project is to develop and… More

This Small Business Innovation Research (SBIR) Phase I project will develop a diagnostic instrument to detect molecular species, such as nitric oxide, in exhaled breath as a biomarker of airway inflammation to assess the effectiveness and compliance of asthma therapies. This project will result… More

DESCRIPTION (Applicant's abstract): Development of a laser-based breath analyzer is proposed for measuring nitric oxide (NO) in exhaled breath of asthmatic patients. Preliminary results using a prototype breath tester demonstrated the feasibility of the proposed technique for measuring trace NO in… More

This Small Business Innovation Research Phase II project will develop a laser based breathmeter for detecting and monitoring asthma in children and adults. The Phase I work proved the feasibility of constructing a machine, based on infrared laser absorption spectroscopy, that is capable of… More

DESCRIPTION (provided by applicant): An innovative instrument for measuring exhaled compounds was demonstrated in Phase I of this project. The novel breath monitor (Breathmeter TM) consists of a tunable mid-IR diode laser, a long optical resonator, and electronics modules for detecting select… More

Bovine Respiratory Disease is the most common illness among cattle arriving at feedlots and results in decreased weight gain, lower quality meat and death. BRD is highly transmittable and costs cattlemen more than all other diseases combined. A rapid and sensitive diagnostic method for BRD is not… More

Bovine Respiratory Disease is the most costly disease among cattle arriving at feedlots and results in decreased weight gain, lower quality meat and death. BRD is highly transmittable and a rapid and sensitive diagnostic method for BRD is not currently available. This project will validate a… More

"The National Research Council has concluded that ammonia is a major concern for air quality at global, national and regional scales. In the US, livestock operations are believed to contribute over 80% of the total emissions of ammonia. Specific interest in ammonia emissions from livestock… More

"This project will test the feasibility of a breath alkane as an indicator of respiratory health in bovine. Significant losses due to bovine respiratory disease (BRD) occur in the U.S. beef industry with estimated annual losses at $1 billion due to higher medical costs, decreased weight gain, lower… More
