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

在主要研究仪器计划和化学部化学研究仪器和设施（CRIF）计划的支持下，弗吉尼亚联邦大学的Massimo Bertino教授及其同事Dexian Ye，Joseph Reiner，埃弗雷特卡彭特和Collen Taylor（后者来自弗吉尼亚州立大学）将获得扫描共焦拉曼显微镜。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端的表面增强拉曼散射;（B）血液和组织中NO的检测;（c）纳米锐体的纳米孔促进装载;（d）功能分级二氧化硅薄膜及其在多个长度尺度上的表征;和（e）气凝胶交联。拉曼光谱测量样品中分子的振动频率，其是材料的化学含量、组成和结构的特征。拉曼显微镜响应于激光探针扫描样品以提供化学组成的空间图像。这种广泛使用的技术，采用激光探测材料，是非破坏性的。该仪器将加强研究生和本科生教育，因为学生在他们的研究项目和实验室课程中使用该仪器。

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.
