2014 REU Poster: Determining the Efficiency of Surface-Enhanced Raman Spectroscopy Substrates in Body Fluid Identification
MetadataShow full item record
A forensic scientist has many goals at a crime scene, including identifying unknown stains (possibly containing body fluids) and collecting evidence for further DNA testing. Body fluid identification is important to understand the nature of the crime and the possible perpetrators. The current methods of body fluid identification include alternate light sources, phenolphthalein, and luminol tests, which can give yield false positive results. A method for overcoming these current limitations is to utilize Raman and surface-enhanced Raman spectroscopy to identify the substance.
