Fluorimeter upgrade

荧光是分子吸收不同颜色的光（能量更高，波长更短）后发出光的一种特性。荧光测量是非常敏感的，在其极限发射可以从单个分子检测到。由于其灵敏度，荧光有许多应用，例如在医疗诊断试剂盒的传感器中。化学家使用荧光作为反应发生效率的诊断工具，并作为探针来了解分子之间如何相互作用。在Bohne基团中，荧光是确定客体如何与超分子系统结合的重要工具。这种表征先于所有动力学研究，以确定来宾与宿主系统的结合动力学。此外，复杂系统荧光研究的专业知识和能力一直是Bohne小组与日本和德国研究人员合作的中心主题。万教授小组专门研究光化学反应是如何发生的。许多化合物在吸收光后（光化学的起始过程）和反应前会发出荧光，这种发射被用作反应效率的诊断工具。两个研究小组目前使用的荧光仪已有10年历史，数据采集和分析是在一台装有专有DOS软件的旧计算机上进行的。要求升级将消除获取荧光数据方面的瓶颈，并将提高有关小组的生产力。

Fluorescence is a property where molecules emit light after absorbing light of a different color (higher energy, shorter wavelength).  Fluorescence measurements are very sensitive and at its limit emission can be detected from a single molecule.  Because of its sensitivity fluorescence has found many applications, as for example in sensors in medical diagnostic kits.  Chemists use fluorescence as a diagnostic tool for how efficiently reactions happen and as probes to understand how molecules can interact with one another.  In the Bohne group fluorescence is an essential tool to establish how guests bind to supramolecular systems.  This characterization precedes all of the kinetic studies to determine the binding dynamics of guests to host systems. In addition, the expertise and ability for fluorescence studies of complex systems has been the central theme for the collaboration of the Bohne group with researchers in Japan and Germany. The Wan group specializes in studying how photochemical reactions happen.  Many of the compounds after absorbing light (initiation process for photochemistry) and before reacting undergo fluorescence and this emission is used as a diagnostic tool for the efficiency of the reactions. The current fluorimeter used by both research groups is 10 years old and data acquisition and analysis is performed on an old computer with proprietary DOS software.  The request for an upgrade would eliminate the bottleneck in the acquisition of fluorescence data and would enhance the productivity of the groups involved.
