Label-free SERS characterization of snake venoms by exploring the cysteine environs with bone-shaped gold nanoparticles

Abstract

Identification of snake venoms is a vital step in the treatment of fatal snakebites. In this study, we use the gold-thiolate interaction between a cysteine residue and gold nanoparticles to...

Differentiation of snake venom using Raman spectroscopic analysis

“…Thus, Raman spectroscopy was used to characterize biochemical alterations in the mouse gastrocnemius that was injected with Bothrops jararacussu venom, as well as, this venom was detected by Raman spectroscopy in the mouse muscle tissue. 30 In another paper, 31 surface-enhanced Raman spectroscopy (SERS) was used to compare and analyze two venoms: Trimeresurus stejnegeri from the Elapidae family and Bungarus multicinctus from the Viperidae family. The SERS fingerprints were different and enough to distinguish the two venoms studied.…”
