The news reporters obtained a quote from the research from CeNS, "The plasmonic properties of the hybrid structure are optically characterized by dark-field imaging and polarization-dependent spectroscopy. SERS measurements on molecules that are embedded in the DNA origami that bridges the nanoantenna gap were performed in order to demonstrate the excellent performance of these structures for enhancing spectroscopic signals. A strong enhancement of the Raman signal was recorded from measurements on single hot spots compared to measurements in bulk."
According to the news reporters, the research concluded: "Finally, we show that the laser polarization with respect to the dimer orientation has a strong impact on the SEAS performance."
