Review on forensic analysis of hair by scanning electron microscope in domestic and wild animals

Analysis and Identification of hair is the most complex and distinct aspect in the field of forensics.The examination of animal hair is a ubiquitous discipline in wildlife forensics. Examination is largely based on microscopy, which enables the hair analyst in identification of hair as animal in origin, to distinguish the hair to a particular species, and to conduct comparative examinations. Analysis of animal remains, e.g. hair at a crime scene helps to provide evidence for contact of a suspected assailant and diagnosing drug expose. The cuticular pattern, cross section and medullary index provides information on the domestic and wild species of the animal. The present review was discussed to investigate some morphological features of hair samples of domesticated and wild animal species using scanning electron microscopy for their identification. Scanning Electron Microscope shows the optical means of identification regarding structural, surface morphology, coupled with scientific data and focuses on species identification.
