Synergistic SERS Enhancement in GaN‐Ag Hybrid System toward Label‐Free and Multiplexed Detection of Antibiotics in Aqueous Solutions (Adv. Sci. 19/2021)

Surface‐Enhanced Raman Spectroscopy In article number 2100640, Yeon Sik Jung, In‐Hwan Lee, and co‐workers demonstrate detection of antibiotics present in aqueous solutions via surface‐enhanced Raman spectroscopy without using any Raman reporter molecules. Using the solvent‐assisted nanotransfer printing technique, ultrafine Ag nanowires are conformally printed on GaN nanopillars to form a metal/semiconductor hybrid structure, which achieves a significant improvement of Raman signals.
