Abstract

Plasmons (quantized, collective oscillations of electrons) have helped to advance methods of chemical analysis in recent decades. Propagating and localized surface plasmons are especially being used in chemical applications and are the focus of this review. The coverage includes the techniques of surface plasmon resonance, optical sensing methods, and surface-enhanced Raman spectroscopy. The frequencies of specific plasmons depend greatly on the structure of the material in which the plasmons reside. Some of these techniques are now available in the chemistry classroom.
