Research Progress in Forensic Body Fluids Identification Based on Nucleic Acid Molecules

Identifying the type and origin of body fluids left at a crime scene is helpful to crime scene reconstruction for it can link the sample donors and actual criminal acts [1]. As Hanson et al. [2] pointed out, the identification of the biological material might be crucial to the prosecution of the case. The appearance of a person's DNA only suggests that he once has been to the crime scene, but his acts were unknown for us.
