The discovery of Raman effect by Sir Chandrasekhara Venkata Raman in 1928 pioneered a new era in the development of spectroscopic technique. The advancement of Raman effect in molecules adsorbed on the surface of noble metal nanoparticles in 1970’s is a milestone for the origin of the Surface Enhanced Raman Spectroscopic (SERS) technique. Fifty years after the discovery of SERS, the term flourished its impact in various fields of biomedical and biosensing applications. The SERS effect is subjected to wide variety of refinement and broadened to many other research areas in analytical world. The production and usage of analytical tools or instruments with ultra-sensitivity and cost effectiveness based on SERS techniques in daily life still demands continuous investigations and research through interdisciplinary approach.
