Identification of animal venoms by Raman spectroscopy
Using Raman spectroscopy, a comparative analysis of venoms from various animals and a number of substances of different nature (not-venoms) was carried out. Animal venom smuggling is a global problem. It is often impossible to prove that the smuggled material is an animal venom. Raman spectroscopy can be used to implement a quick and simple method for identifying dry animal venoms. We demonstrated that Raman spectroscopy combined with principal component analysis (PCA) can distinguish between crude venom and not-venom samples, as well as cluster different animal venoms based on their similarities. The proposed method appears promising for on-site venom identification, for example, at border controls. Learn more
