Patent abstract

The present invention relates generally to the field of spectroscopy, and more particularly to tip-enhanced Raman spectroscopy that provides an enhanced contrast-ratio of a near-field Raman signal to a background signal. The near-field Raman signal is captured from a small volume of material near a metal-coated tip thereby achieving submicron lateral resolution.
