*** 9660152 Kaiser This project is focused on development of a new class of chemical sensors for detection of a variety of volatile organic carbon (VOC) pollutants, including chlorinated hydrocarbons. The ability to accurately and reliably achieve molecular discrimination between various VOC's will be based on a polymeric monolayer utilizing a new class of polymers called Starburstd9 dendrimers. This project will systematically examine the relationship between the dendritic structure and chemical composition of these nanoscopic-sized spheroidal polymers and their ability to differentiate between chemical molecules with a variety of functional groups. A designed series of dendritic polymers will be synthesized and will be covalently attached to a gold surface to form a self-assembled monolayer, and the suitability of the dendrimer to act as a chemically sensitive interface will be determined by challenging dendrimer-modified surface acoustic wave (SAW) mass balances with vapor-phase probe molecules. This will facilitate development of new sensor technology by elucidation of molecular mechanisms and response optimization. This technology could permit development of reliable, application-specific detectors in areas such as: health and safety monitoring, environmental remediation, industrial process control and auto emissions. ***

* 9660152 Kaiser 该项目的重点是开发一种新的化学传感器，用于检测各种挥发性有机碳（VOC）污染物，包括氯化烃。准确可靠地实现各种VOC之间的分子区分的能力将基于利用称为Starburstd9树枝状聚合物的新型聚合物的聚合物单层。该项目将系统地研究这些纳米级球形聚合物的树枝状结构和化学组成之间的关系，以及它们区分具有各种官能团的化学分子的能力。一系列设计的树枝状聚合物将被合成，并将共价连接到金表面，形成自组装单层，和适合的树枝状聚合物作为一个化学敏感的接口将确定挑战树枝状聚合物改性的表面声波（SAW）质量平衡与气相探针分子。这将有助于开发新的传感器技术，阐明分子机制和响应优化。 该技术可以在健康和安全监测、环境修复、工业过程控制和汽车排放等领域开发可靠的特定应用探测器。 ***
