Characterization of Bloodstains
The objective of this project is to develop a probe based Raman system along with automated algorithm to select features for characterization of bloodstains in presence of interference from the substrate background for forensic application. Specifically, we seek to: (1) identify biomarkers associated with aging of bloodstains using Raman micro-spectroscopy, (2) develop a regression model to predict the age of the bloodstains using selective spectral markers, and (3) design a portable probe based Raman system for on-site measurements. Biochemical characterization of bloodstains is being accomplished using Raman spectroscopy. The bloodstains will be evaluated in presence of interference from substrates. A probe based Raman system will be developed for real scenario application.
