Purchase of a Picosecond Fluorescence Spectrometer

化学研究仪器和设施(CRIF)计划的这一奖项将使伊利诺伊大学香槟分校的化学系能够购买一台皮秒荧光光谱仪。该设备将主要由初级教员Christopher Bardeen使用，他的研究重点是使用具有高时间和空间分辨率的光学技术来观察材料科学和生物学中复杂系统的动力学。具体地说，巴丁博士将研究共轭聚合物中的能量和电荷传输的动力学，以及光敏剂在生物介质中的光化学。在材料科学中，共轭聚合物和低聚物在发光二极管和平板显示器中的应用引起了人们的兴趣。在生物学中，荧光染料通常被用作细胞内生化检测的标记。最近，光敏剂已被用于包括癌症在内的许多疾病的治疗，这一过程被称为光动力疗法。

This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program will enable the Department of Chemistry at the University of Illinois in Urbana-Champaign to purchase a picosecond fluorescence spectrometer. This equipment will be used primarily by junior faculty member Christopher Bardeen, whose research focuses on the use of optical techniques with high temporal and spatial resolution to observe dynamics in complex systems in materials science and biology. Specifically, Dr. Bardeen will study the dynamics of energy and charge transport in conjugated polymers; and the photochemistry of photosensitizers in biological media. In materials science, conjugated polymers and oligomers are of interest for applications in light emitting diodes and flat panel displays. In biology, fluorescent dyes are commonly used as labels for examination of intracellular biochemistry. More recently, photosensitizers have been used for the treatment of many diseases, including cancer, in a procedure known as photodynamic therapy.
