This Small Business Innovation Research (SBIR) Phase I project will lead to the development of a new class of liquid crystal (LC)-based direct-read monitors (DRMs) for detection of nitrogen dioxide (NO2) present in air at construction sites. The approach to development of DRMs that is described in this proposal is based on the innovative use of LC materials to detect and report molecular interactions on chemically functionalized surfaces. Results obtained under Phase I research will demonstrate that sensors comprised of a chemically functionalized surface supporting a thin film of nematic LC can detect NO2 in air at levels required to meet worker safety standards established by regulatory agencies.The broader impact of this research is the reduction of hazardous chemicals exposure risk to 139 million US citizens at their work place. This Phase I SBIR proposal is focused on protecting the health of 9 million workers in the US construction industry, workers who have been documented to be at increased risk of chronic exposure to NO2 in air due to regular use of various tools, equipments, and vehicles powered by diesel engines. This DRM platform, while initially focused on detection of NO2 within construction zones, has the potential to be broadly useful for detection of a range of hazardous gases encountered in occupational settings in the US.

这项小型企业创新研究（SBIR）第一阶段项目将开发一种新型的基于液晶（LC）的直接读取监测器（DRM），用于检测建筑工地空气中的二氧化氮（NO2）。本提案中描述的DRM开发方法是基于LC材料的创新使用，以检测和报告化学功能化表面上的分子相互作用。第一阶段研究的结果将证明，由化学功能化表面支撑的N2O3 LC薄膜组成的传感器可以检测空气中的NO2，其水平符合监管机构制定的工人安全标准。这项研究的更广泛影响是减少1.39亿美国公民在工作场所接触危险化学品的风险。第一阶段SBIR提案的重点是保护美国建筑业900万工人的健康，这些工人因经常使用各种工具，设备和柴油发动机驱动的车辆而被记录为慢性暴露于空气中NO2的风险增加。该DRM平台最初专注于检测建筑区域内的NO2，但有可能广泛用于检测美国职业环境中遇到的一系列有害气体。
