How Surface-Enhanced Raman Scattering Amplifies Signals for Trace Detection

Quick fact

SERS can enhance Raman signals by factors of 10^10 to 10^11, enabling the detection of single molecules—a level of sensitivity that no other vibrational spectroscopy can match without amplification.

Why this is interesting

You’ve probably seen Raman spectroscopy described as a powerful tool—but what if you could only detect one molecule out of a billion? That’s where surface-enhanced Raman scattering (SERS) comes in, boosting the signal by up to ten orders of magnitude.
