项目摘要

Recent advances in analytical chemistry have been directed to the development of miniaturised instrumentation, low-concentration sensing technologies, and cost-effective solutions. While optical and spectroscopic sensing components, such as lasers and photodetectors, have become more widely available, there is still much work to be done to develop advanced systems with analytical-grade performance, robustness, self-calibration and low-power consumption. The main limitations are the high sensitivity and selectivity required for the detection of tiny amounts of analytes in complex sample mixtures, and the requirement for continuous and fast-response measurements.The project will develop new analytical techniques and sensors based on optical spectroscopies, nano- and micro-structures, photonic and waveguide structures, combined with surface-enhanced and electrochemical methods. Combining optical and electrical information, i.e. for more than one physical/chemical property, can provide accurate and detailed insights into molecular structure and function. In addition, as a part of this project, the interaction of the analyte with the sensor surface will be studied and designed, as it plays a key role in determining sensor performance. The sensor technologies will be demonstrated for a range of applications in healthcare and medicine, safety and security, food quality control, waste, emissions, and the chemical-process industry.

分析化学领域的最新进展主要集中在仪器化、低浓度传感技术和成本效益解决方案的开发上。虽然激光器和光电探测器等光学和光谱传感元件已变得越来越广泛，但要开发具有分析级性能、鲁棒性、自校准和低功耗的先进系统，仍有许多工作要做。主要的局限性是在复杂样品混合物中检测微量分析物所需的高灵敏度和选择性，以及连续和快速响应测量的要求，该项目将开发基于光谱学、纳米和微米结构、光子和波导结构的新分析技术和传感器，并结合表面增强和电化学方法。结合光学和电学信息，即一种以上的物理/化学性质，可以提供对分子结构和功能的准确和详细的了解。此外，作为该项目的一部分，将研究和设计分析物与传感器表面的相互作用，因为它在决定传感器性能方面起着关键作用。传感器技术将在医疗保健和医药、安全和安保、食品质量控制、废物、排放和化学加工行业的一系列应用中得到展示。
