Abstract

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.
