    • Amino β-cyclodextrins immobilized on gold surfaces: Effect of substituents on host-guest interactions 
      Méndez-Torres, Ana; Sandoval Altamirano, Catalina; Sánchez-Arenillas, María; Marco, José; Yáñez, Claudia (Elsevier Ltd, 2018)
      In the present paper we describe a simple method to immobilize amino cyclodextrins (CDs) and methylated-amino cyclodextrins on gold surfaces. We also report on the effect that the presence of methyl groups in the broader ...
    • Cu@Au self-assembled nanoparticles as SERS-active substrates for (bio)molecular sensing 
      Cabello, Gema; Nwoko, Kenneth C.; Marco, José F.; Sánchez-Arenillas, María; Méndez-Torres, Ana María; Feldmann, Jorg; Yáñez, Claudia; Smith, Tim A.D. (Elsevier Ltd, 2019)
      Cu0(core)-Au0(shell) (Cu@Au) bimetallic nanoparticles (NPs) synthesized under microwave-assisted heating were interrogated for surface enhanced Raman scattering (SERS)-active substrates. NPs characterization, by XRD, XPS ...
    • Cyclic voltammetric and EQCM study of the behaviour and stability of Pt-Ir deposits and Pt-Ir wire electrodes ... 
      Ureta Zañartu, María Soledad; Bravo, P.; Reyes Cava, Gloria Ximena; Yañez, Claudia; Gancedo, José Ramón; Gutiérrez, C.; Marco, José F. (SOCIEDAD CHILENA DE QUIMICA, 2001-09)
      The electro-oxidation of methanol at Pt-Ir and Pt deposits, and at Pt, Ir, and Pt-Ir wires in sulfuric acid solution was studied by cyclic voltammetry (CV), and in the case of Pt-Ir and Pt electrodeposits, also with the ...
    • Electrodes Based on Zeolites Modified with Cobalt and/or Molybdenum for Pesticide Degradation. Part I: ...

      In this work, we report a new octanuclear cluster based on FeIII and the ligand 1H-imidazole-4,5-dicarboxylic acid, [Et3NH](12)[Fe-8(IDC)(12)]center dot 10DMF center dot 13H(2)O (1), with a metal core containing eight ...
    • Reduced graphene oxides: influence of the reduction method on the electrocatalytic effect towards nucleic ... 
      Báez, Daniela F.; Pardo, Helena; Laborda, Ignacio; Marco, José F.; Yañez Soto, Claudia; Bollo Dragnic, Soledad (MDPI, 2017)
      For the first time a critical analysis of the influence that four different graphene oxide reduction methods have on the electrochemical properties of the resulting reduced graphene oxides (RGOs) is reported. Starting from ...
    • Silica-coated magnetite nanoparticles functionalized with betaine and their use as an adsorbent for Mo(VI) ... 
      Alfaro, Ian; Molina, Lorena; González, Pablo; Gaete, José; Valenzuela, Fernando; Marco, José F.; Sáez, César; Basualto, Carlos (Korean Society of Industrial Engineering Chemistry, 2019)
      The aim of this work is to produce a superparamagnetic core-shell adsorbent material composed of magnetite nanoparticles coated with a silica layer and functionalized with betaine for applications associated with the ...
