The objectives of this project are to develop the concepts for robust multiplexed arrays of sensors for the detection of inorganic and organic analytes as well as microorganisms and to develop instrumentation to quantify heterogeneous kinetics and molecule/surface interactions in complex, groundwater and surface water, and extreme ecosystems. Electrochemical, Surface Plasmon Resonance (SPR) and Surface Enhance Raman Spectroscopy (SERS) method will be used as detection schemes for the quantification of inorganic and organic analytes in hydrothermal fluids. The development of robust polymeric thin film sensors will be assisted by current Hydrothermal Atomic Force Microscopy (AFM) instrumentation. The investigators will also further the development of the AFM instrumentation to enable intermittent-contact imaging of "soft" materials and surface adsorbed molecules and organisms in hydrothermal conditions. Groundwork will be laid for the development of a low-power, lightweight AFM for potential development into a field-deployable instrument.%%%The results from this project could lead to new methods for obtaining chemical and biological information from complex ecosystems. Furthermore, the research will be used to enhance educational opportunities in this growing field of scientific discovery. Students trained in these areas will be very competitive in the job market as these are areas of high priority in industry.

该项目的目标是开发用于检测无机和有机分析物以及微生物的强大的多路复合传感器阵列的概念，并开发用于量化复杂、地下水和地表水以及极端生态系统中的非均相动力学和分子/表面相互作用的仪器。电化学、表面等离子体共振(SPR)和表面增强拉曼光谱(SERS)方法将被用作热液流体中无机和有机分析物的定量检测方案。目前的水热原子力显微镜(AFM)仪器将帮助开发坚固耐用的聚合物薄膜传感器。研究人员还将进一步开发原子力显微镜仪器，以便能够在水热条件下对“软”材料和表面吸附的分子和生物体进行间歇接触成像。将为开发一种低功率、轻量化的原子力显微镜奠定基础，使其有可能发展成为可现场部署的仪器。该项目的结果可能导致从复杂生态系统中获取化学和生物信息的新方法。此外，这项研究将用于在这一日益增长的科学发现领域增加教育机会。受过这些领域培训的学生将在就业市场上具有很强的竞争力，因为这些领域是工业中的优先领域。
