Optofluidic Raman Spectroscopy for Chemical Analysis and Raman Spectroscopy Bio-Sensor for Tissue Analysis

抽象的

拉曼光谱学是用于化学指纹识别的生物化学分析领域的强大光谱工具。该技术实现多组分检测的能力使得该技术具有高化学特异性。然而，拉曼散射的弱横截面使得具有敏感的探测器和有效的光学系统来确保拉曼光子的最高光通量，同时拒绝尽可能多的背景发光。最近的来源，探测器和探头技术进步使得可以减少拉曼仪器的形状因素，这允许用于化学分析和临床诊断的现场便携性。该谈话解决了化学分析和临床诊断中拉曼光谱的两个方面。

该谈话的第一部分详细说明了完全光学取向的紧凑型光学器流体装置，以从小体积（约10微升）的流体进行拉曼光谱。将详细使用该装置进行各种分析物检测和反应监测。此外，将使用该装置在食品和饮料行业中使用这种装置，用于使用该装置进行苏格兰威士忌分析和检测酒精饮料中的毒性。

The second part of this talk details a Raman spectroscopy bio-sensor which was designed to be integrated with a surgical robot for tissue analysis. The design constraints to achieve such a system would be detailed and would discuss the issue of data representation when using Raman spectroscopy for clinical diagnostics.
