Biosensors, also known as labs-on-a-chip, are bioanalytical devices designed for use in personalized medicine, rapid medical diagnostics, drug discovery and environmental analysis. Most biosensors work by chemically detecting specific "biomolecular markers" such as pathogens or environmental contaminants. There are many applications, however, for which no reliable markers can be found. In such cases, "higher-level" biosensors based on live biological cells are a powerful alternative. Indeed, cells are complex self-contained miniaturized machines that can be used as the basis for biosensing, where the cell response to its environment is in itself the sensing mechanism. Recent advances in nanotechnology and theoretical understanding of sub-wavelength phenomena in plasmonics have opened up many new and exciting possibilities for miniaturized biosensing. My research program over the next 5 years seeks to capitalize on these advances by developing novel high-resolution multi-modal instrumentation designed to discover new enabling knowledge on how cells react to changes in their local environment in response to the presence of disease factors, pathogens, or contaminants. This new knowledge will lead to the development of next-generation cell-based biosensors designed to address some of the most pressing needs in critical care and personalized medicine.*** **

生物传感器，也称为芯片实验室，是设计用于个性化医疗，快速医疗诊断，药物发现和环境分析的生物分析设备。大多数生物传感器通过化学检测特定的“生物分子标记”，如病原体或环境污染物。 然而，有许多应用无法找到可靠的标记。在这种情况下，基于活生物细胞的“更高级别”生物传感器是一个强大的替代方案。事实上，细胞是复杂的独立微型机器，可以用作生物传感的基础，其中细胞对其环境的反应本身就是传感机制。纳米技术的最新进展和对等离子体子波长现象的理论理解为小型化生物传感开辟了许多新的和令人兴奋的可能性。我在未来5年的研究计划旨在通过开发新型高分辨率多模态仪器来利用这些进展，旨在发现细胞如何对疾病因素，病原体或污染物的存在对其局部环境的变化做出反应的新知识。这些新知识将导致下一代基于细胞的生物传感器的开发，旨在解决重症监护和个性化医疗中一些最迫切的需求。 **
