Raman Spectroscopy as a Universal Analytical Technique for Bodily Fluids

In this interview, Professor Igor K. Lednev discusses the potential of Raman spectroscopy to replace biochemical tests as a universal analytical technique for bodily fluids (biological stains) in forensic science. This interview conducted at Pittcon 2019.

Now, nearly 30 years later, a team of scientists at the University of Missouri is using this same sonar technology as inspiration to develop a rapid, inexpensive way to determine whether the drinking water is safe to consume. Based on their results, the scientists said they can determine changes in the physical properties of liquids.

	Forensic Confirmation Bias (Cognitive Bias in Forensics) For the past decade, considerable discussion has been made on the extent to which cognitive bias can impact how decisions are made in forensics. Although cognitive bias can arise naturally for a number of different reasons, significant consequences - including incorrect conclusions, overstatements and impartial decisions - may occur.

	Analytical Techniques Employed in Microbial Forensics Microbial forensics is a subfield of forensics that involves the application of scientific techniques to characterize microbial evidence related to an act of bioterrorism, biocrime or the accidental release of a microbial agent or toxin.

	Mass Spectrometry as a Tool in Forensic Science Mass spectrometry is a highly sensitive and versatile tool that is commonly used by forensic scientists for the screening and identification of known and unknown substances. In mass spectrometry, a sample is analyzed to determine its molecular composition through the generation of a spectrum that reveals the masses of its component parts.
