Spectroscopy Spotlight
Lasers are used for a wide range of industrial, medical, spectroscopic, and military applications. Daniel Kazal, a graduate research assistant in the Department of Chemistry and Biochemistry at the University of Maryland Baltimore County, has developed a novel technique for channeling sound using a tube-shaped laser beam that forms a thermal gradient. Based on his work with this approach, he received the 2017 FACSS Innovation Award. We recently spoke with him about this research. This interview is part of a series of interviews with the winners of awards presented at SciX. read more

Depth profiling of a Nicotine patch by Raman microscopy
Transdermal patches have multiple layers: the release liner, the adhesive, the membrane, and the backing. It is important to understand the composition of a patch to perform quality control, make product improvements, and to monitor drug release. Traditional methods of analysis are destructive, requiring extraction or cross-sectioning. This application note shows how confocal Raman microscopy examines product layers without sample destruction.
