Portable Raman Spectroscopy in Forensics: Explosive Residues and Inflammable Liquids

Forensics and forensic science are highly popular terms nowadays thanks to famous TV series and films. Most people, inspired by these series, normally associate these terms to crime scene investigation (CSI), ocular inspection and evidence recovery. However, forensics involves much more than CSI, including a vast number of sciences, disciplines and studies such as forensic genetics, chemistry, informatics, anthropology, entomology, ballistics, dactylography, questioned documents, acoustics and linguistics. Each forensic discipline deals with perfectly delimited evidence and performs highly particular studies to provide specific information about certain aspects of the crime investigation to such an extent that a certain discipline might be completely decisive in some crimes but totally dispensable in others [1].
