With support from the Major Research Instrumentation (MRI) Program, Prof. Emanuel Waddell of Morgan State University will develop an in-situ near infrared Raman probe laser ablation system for chemistry research. This multi-wavelength pulsed UV laser ablation system with a controllable xy-stage will allow for the fabrication of microfluidic systems and analytical sensors in polymer substrates. It will also be capable of performing in-situ investigations of the polymer surface via near infrared Raman spectroscopy. The instrument will result in a clearer understanding of the surface chemistry that results as a function of laser ablation, and will provide insight into the effects of local atmosphere and ablation wavelength on the resulting moieties on the polymer surface. The in-situ near infrared Raman proble laser ablation system is a unique instrument as it will allow the in-situ, real-time investigation of the polymer surface during the ablation process. The near-infrared Raman analysis will provide a nondestructive method to probe chemical reactions on the polymer surface. Development of this instrument will significantly enhance research in the polymer sciences.

摩根州立大学的Emanuel Waddell教授在重大研究仪器（MRI）计划的支持下，将开发一种用于化学研究的原位近红外拉曼探针激光烧蚀系统。 这种多波长脉冲紫外激光烧蚀系统与可控的xy阶段将允许在聚合物基板的微流体系统和分析传感器的制造。 它还将能够通过近红外拉曼光谱对聚合物表面进行原位研究。 该仪器将导致作为激光烧蚀的函数的结果的表面化学的更清楚的理解，并将提供洞察局部大气和烧蚀波长对聚合物表面上的所得部分的影响。原位近红外拉曼探针激光烧蚀系统是一种独特的仪器，因为它将允许在烧蚀过程中的聚合物表面的原位，实时调查。 近红外拉曼分析将提供一种非破坏性的方法来探测聚合物表面上的化学反应。 该仪器的开发将大大加强聚合物科学的研究。
