Abstract
A substrate for surface enhanced Raman spectroscopy analysis (SERS) comprises a ferroelectric single crystal having polarization-inverted patterns of spontaneous polarizations including polarization-inverted portions and non-inverted polarization portions, and metallic dots positioned at only either one polarized surfaces of the polarization-inverted portions and the non-inverted polarization portions. The provided SERS substrate produces a high enhancement effect. A microfluidic device incorporating the SERS substrate is also provided.
