Flexible plasmonic substrate for sensitive surface-enhanced Raman scattering-based detection of fentanyl

Chem. Commun., 2024, Accepted Manuscript DOI: 10.1039/D4CC04988H, Communication Yun-Tzu Hsu, Shih-Han Lin, Keng-Ku Liu In this work, we demonstrate a straightforward and versatile approach for fabricating flexible SERS substrates for highly sensitive fentanyl detection. Our design strategy integrates the synthesis of yolk-shell structured plasmonic...
