MRI: Acquisition of an imaging Raman spectrometer for research and training

弗吉尼亚联邦大学的Massimo Bertino教授和他的同事desian Ye、Joseph Reiner、Everett Carpenter和Collen Taylor（后者来自弗吉尼亚州立大学）将获得一台扫描共聚焦拉曼显微镜。该提案旨在加强各级的研究和教育，特别是在以下领域：(a)贵金属涂层金属纳米尖上的表面增强拉曼散射；(b)血液和组织中NO的检测；(c)纳米孔促进纳米尖的加载；(d)功能梯度二氧化硅薄膜及其在多长度尺度上的表征；(e)气凝胶交联。拉曼光谱测量样品中分子的振动频率，这些频率是材料的化学成分、组成和结构的特征。拉曼显微镜扫描样品，以提供响应于激光探针的化学成分的空间图像。这种广泛使用的技术，利用激光探测材料，是非破坏性的。当学生在他们的研究项目和实验课程中使用该仪器时，该仪器将加强研究生和本科生的教育。

With support from the Major Research Instrumentation Program and the Chemistry Research Instrumentation and Facilities (CRIF) Program of the Chemistry Division, Professor Massimo Bertino from Virginia Commonwealth University and colleagues Dexian Ye, Joseph Reiner, Everett Carpenter and Collen Taylor (the latter from Virginia State University) will acquire a scanning confocal Raman microscope. The proposal is aimed at enhancing research and education at all levels, especially in areas such as (a) surface-enhanced Raman scattering on noble metal coated metal nanotips; (b) detection of NO in blood and tissue; (c) nanopore-facilitated loading of nanosharps; (d) functionally-graded silica films and their characterization on multiple length scales; and (e) aerogel cross-linking.Raman spectroscopy measures the vibrational frequencies of molecules in a sample which are characteristic of the chemical content, composition and structure of the material. A Raman microscope scans across a sample to provide a spatial image of the chemical composition in response to the laser probe. This widely used technique, employing lasers to probe the material, is non-destructive. This instrument will strengthen graduate and undergraduate education as students use this instrument in their research projects and in laboratory courses.
