A new method for accurately analyzing body fluids at crime scenes has been developed by scientists. The breakthrough technology could help investigators to quickly identify the type of fluid involved in a crime, without the need for traditional lab testing. The research team has developed a method that uses a combination of infrared and Raman spectroscopy to analyze body fluids in a much shorter time than traditional techniques. This could be a crucial tool for forensic investigators, as it could help them to quickly identify the type of fluid at a crime scene and determine whether it is blood, saliva, or another type of body fluid. This could help investigators to find evidence that could lead to a conviction.
