Forensic Chemistry 

TL;DR: Wipe sampling of the exterior of bags of questioned powders is shown to be a safe alternative method for field screening and identification, removing the need to handle potentially lethal amounts of material.

TL;DR: In this paper, the authors combined the specificity of Raman spectroscopy with the analytical power of statistical modeling to develop a universal, confirmatory, non-destructive, approach that can be used to differentiate and identify body fluids.

TL;DR: In this paper, a review of recent developments in Raman spectroscopy with regards to forensic science is presented, including chemometrics, controlled substances, toxicology, counterfeit pharmaceuticals, explosives, gunshot residue, hair, fibers, paints, lipstick and nail polish, body fluids, forensic anthropology, and document examination.

TL;DR: This article presents a review of research demonstrating the use of DART-MS for forensically relevant samples over the past five years, and background on the technique, sampling approaches, and data analysis methods are presented.

TL;DR: This work summarizes a proof-of-concept study demonstrating the effectiveness of using Raman spectroscopy to nondestructively analyze bloodstains, and probe for specific kinetic changes in aged bloodstain for up to two years.
