    • AOT Retrieval Procedure for Distributed Measurements With Low-Cost Sun Photometers 
      Toledo, F.; Garrido, C.; Díaz, M.; Rondanelli, R.; Jorquera S., Leila; Valdivieso, P. (Blackwell Publishing Ltd, 2018)
      We propose a new application of inexpensive light-emitting diode (LED)-based Sun photometers, consisting of measuring the aerosol optical thickness (AOT) with high resolution within metropolitan scales. Previously, these ...
    • Hospitalizations for asthma exacerbation in Chilean children: A multicenter observational study 
      Herrera, A. M.; Brand, P.; Cavada, G.; Koppmann, A.; Rivas, M.; Mackenney, J.; Sepúlveda, H.; Wevar, M. E.; Cruzat, L.; Soto, S.; Pérez, M. A.; León, A.; Contreras, I.; Alvarez, C.; Walker, B.; Flores, C.; Lezana, V.; Garrido, C.; Herrera, M. E.; Rojas, A.; Andrades, C.; Chal (Elsevier Doyma, 2018)
      © 2018 SEICAPBackground: Asthma hospitalization rates in Chilean children have increased in the last 14 years, but little is known about the factors associated with this. Objective: Describe clinical characteristics of ...
    • Molecular dynamics characterization of silver colloidal interfaces for SERS applications. Gallic acid test 
      Muñoz Gacitúa, D.; Garrido, C.; Ruíz Fernández, A.; Ahumada, H.; Campos Vallette, Marcelo; Araya Maturana, Ramiro; Weiss López, Boris (Wiley, 2018)
      One of the most useful applications of silver colloidal solutions is in surface-enhanced Raman spectroscopy (SERS), because the amplification factor of about 10(6) allows the vibrational study and detection of highly diluted ...
    • Multiple sclerosis during COVID-19 pandemic in Santiago, chile 
      Guevara, C.; Villa, E.; Cifuentes, M.; Martínez, M.; Garrido, C.; Díaz V., Erika; Silva Rosas, Carlos; Naves Pichuante, Rodrigo; De Grazia Kunstmann, José (Sage, 2020)
    • 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 study of the antioxidant alkaloid boldine using prismatic silver nanoparticles 
      Herrera, M .A.; Jara, G. P.; Villarroel, R.; Aliaga, A. E.; Gómez Jeria, Juan; Clavijo Campos, Ernesto; Garrido, C.; Aguayo, T.; Campos Vallette, Marcelo (Elsevier, 2013)
      Prismatic silver nanoparticles (PNps) were used in the surface enhanced Raman scattering (SERS) study of the antioxidant alkaloid boldine (5,6,6a,7-tetrahydro-1,10-dimethoxy-6-methyl-4H-dibenzo[de,g]quinoline-2,9-diol). ...
    • Surface-enhanced Raman scattering activity of negatively charged bio-analytes from a modified silver colloid 
      Garrido, C.; Weiss López, Boris; Campos Vallette, Marcelo (Taylor and Francis Inc., 2016)
      A modification to the traditional synthesis of reduced silver metal nanoparticles with hydroxylamine hydrochloride is proposed. The new colloid, obtained by decreasing the concentration of hydroxide and chloride ions, is ...
    • 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 and theoretical study of the bilichromes biliverdin and bilirubin 
      Celis, F.; Campos Vallette, Marcelo; Gómez Jeria, Juan; Clavijo Campos, Ernesto; Jara, G. P.; Garrido, C. (Taylor and Francis Inc., 2016)
      © 2016, Copyright © Taylor & Francis Group, LLC. The surface-enhanced Raman scattering spectra of biliverdin and bilirubin were obtained and analyzed; a physical silver ligand interaction was inferred. The structural ...
    • 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 ...
    • Treatment, outcomes and costs of asthma exacerbations in Chilean children: a prospective multicenter ... 
      Herrera, A. M.; Brand, P.; Cavada, G.; Koppmann, A.; Rivas, M.; Mackenney, J.; Sepúlveda, H.; Wevar, M. E.; Cruzat, L.; Soto, S.; Pérez, M.
