| description | This article reviews some recent development and application of some powerful and relatively new Raman spectroscopic methods in the forensic science field. Surface-enhanced Raman spectroscopy has been employed for the sensitive analysis of trace amounts of controlled substances. Shifted-excitation Raman difference spectroscopy has been utilized to get fluorescence-background free Raman spectra for some forensic evidence. And spatially offset Raman spectroscopy has been deployed to analyze surface materials, such as explosives and drugs, directly through surface packaging and container materials. Some of these methods have been combined to produce even more powerful tools for some very complicated forensic investigation scenarios. All these methods are very promising in aiding forensic analysis, helping ensure fair administration of justice and security. |
