    • Fluorescence and surface-enhanced vibrational spectroscopies of lawsone and plumbagin 
      Aliaga, A. E.; Leyton, P.; Clavijo Campos, Ernesto; Campos Vallette, Marcelo (Taylor and Francis Inc., 2016)
      © 2016, Copyright © Taylor & Francis Group, LLC. The natural dyes lawsone and plumbagin (1,4-naphthoquinones) were studied by using fluorescence, Raman, infrared (IR), surface-enhanced Raman scattering (SERS), and ...
    • SERS spectrum of red dyes in the Mapuche belts from the beginning of the XXth century 
      Campos Vallette, Marcelo; Rodríguez, M. J.; Chapanoff, M. A.; Clavijo Campos, Ernesto; Gómez Jeria, Juan; Aliaga, A. E.; Jara, G. P.; Celis, F.; Paipa, C.; Leyton, P. (Wiley, 2017)
      Red dyes in seven belts (trariwe) belonging to the Mapuche culture, dated as beginning of the XXth century and stored in Museo Regional de la Araucania, Chile, were studied by using ultraviolet-visible, liquid chromatography ...
    • Surface enhanced Raman scattering study of l-lysine 
      Aliaga, A. E.; Osorio Román, Igor; Garrido, C.; Leyton, P.; Cárcamo Vega, José; Clavijo Campos, Ernesto; Gómez Jeria, Juan; Díaz Fleming, Guillermo; Campos Vallette, Marcelo (2009)
      Different SERS spectra of lysine (Lys) in Ag colloidal surface were obtained. No identical SERS spectra of Lys were observed after a stabilization period, suggesting that a unique conformation and orientation on the metal ...
    • Surface-enhanced Raman scattering and theoretical studies of the C-terminal peptide of the β-subunit human ... 
      Aliaga, A. E.; Aguayo, T.; Garrido, C.; Clavijo Campos, Ernesto; Hevia, E.; Gómez Jeria, Juan; Leyton, P.; Campos Vallette, Marcelo; Sánchez Cortés, S. (2011)
      Raman and surface-enhanced Raman scattering (SERS) spectra of the synthetic carboxy terminal peptide of human chorionic gonadatropin β-subunit free of carbohydrate moieties (P37) are reported. The spectral analysis is ...
    • Surface-enhanced Raman scattering study of L-tryptophan 
      Aliaga, A. E.; Osorio Román, Igor; Leyton, P.; Garrido, C.; Cárcamo, J.; Caniulef, C.; Célis, F.; Díaz Fleming, Guillermo; Clavijo Campos, Ernesto; Gómez Jeria, Juan; Campos Vallette, Marcelo (2009)
      Surface-enhanced Raman scattering (SERS) spectra of tryptophan (Trp) were obtained. A unique SERS spectrum of Trp, corresponding to the most stable conformation and orientation on the metal surface, is observed after a ...
