DESCRIPTION (provided by applicant): This small business innovation research Phase I project will be used to demonstrate the feasibility of developing a reversible sensor to measure carbon monoxide at very low levels (5 parts per million or lower) where existing devices fail. Aside from the elderly population, carbon monoxide is especially dangerous (even at low levels) for unborn babies, infants, and children who are at much greater risk from exposure because they have smaller bodies, faster metabolisms, and they absorb carbon monoxide quicker. When a fetus is exposed to carbon monoxide, the toxic gas destroys vital oxygen cells, interfering with the brain's development - the organ that require the most oxygen. According to experts, toxic levels of carbon monoxide can be up to ten times higher in the fetus than the mother. In this project innovative indicator formulations will be incorporated as thin film on optical substrates. The Phase I working model will be tested for a variety of performance parameters including sensitivity, response time, accuracy, precision, resolution and interferences.

该小型企业创新研究第一阶段项目将用于证明开发可逆传感器的可行性，以在现有设备失效的情况下测量极低水平（百万分之五或更低）的一氧化碳。除了老年人之外，一氧化碳对未出生的婴儿，婴儿和儿童尤其危险（即使在低水平下），因为他们的身体较小，新陈代谢更快，吸收一氧化碳更快。当胎儿暴露在一氧化碳中时，有毒气体会破坏重要的氧细胞，干扰大脑的发育--大脑是需要氧气最多的器官。据专家介绍，胎儿体内一氧化碳的毒性水平可能比母亲高出十倍。在这个项目中，创新的指示剂配方将作为薄膜在光学基板上。将对I期工作模型的各种性能参数进行测试，包括灵敏度、响应时间、准确度、精密度、分辨率和干扰。
