Copper nanoparticles unexpectedly prove suitable for ultraviolet SERS spectroscopy

Lithuanian researchers at the Center for Physical Sciences and Technology (FTMC), Habil. Dr. Gediminas Niaura and Dr. Martynas Talaikis, together with international colleagues, have for the first time demonstrated that copper is a suitable metal for ultraviolet surface-enhanced Raman spectroscopy (UV SERS)—a highly sensitive method used to study molecular vibrations.
