在主要研究仪器(MRI)计划的支持下，摩根州立大学的Emanuel Waddell教授将开发一种用于化学研究的就地近红外拉曼探针激光消融系统。这种具有可控XY平台的多波长脉冲UV激光烧蚀系统将允许在聚合物衬底上制造微流控系统和分析传感器。它还将能够通过近红外拉曼光谱对聚合物表面进行现场研究。该仪器将使人们更清楚地了解激光烧蚀导致的表面化学，并将深入了解局部大气和烧蚀波长对聚合物表面所产生的部分的影响。原位近红外喇曼激光烧蚀系统是一种独特的仪器，它可以在烧蚀过程中对聚合物表面进行原位、实时的研究。近红外拉曼分析将为探测聚合物表面的化学反应提供一种无损的方法。该仪器的开发将大大加强聚合物科学的研究。

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.
