    • Determination of chemical rate constants in singlet molecular oxygen reaction by using 1,4-dimethylnaphthalene ... 
      Günther, S.; Lemp Miranda, Else; Zanocco Loyola, Antonio (2002)
      Thermal decomposition of 1,4-dimethylnaphthalene endoperoxide (DMNE) as a source of singlet oxygen was used to measure chemical rate constants, k(R), for reactions between singlet oxygen, O-2((1)Delta(g)), and various ...
    • Naphthoxazole-Based Singlet Oxygen Fluorescent Probes 
      Ruiz González, Rubén; Zanocco, Renzo P.; Gidi, Yasser; Zanocco Loyola, Antonio; Nonell, Santi; Lemp Miranda, Else (The American Society of Photobiology, 2013)
      In this study, we report the synthesis and photochemical behavior of a new family of photoactive compounds to assess its potential as singlet oxygen (1O2) probes. The candidate dyads are composed by a 1O2 trap plus a ...
    • Photophysics and Photochemistry of Naphthoxazinone Derivatives 
      Nonell, Santi; Ferreras, Lourdes R.; Cañete, Alvaro; Lemp Miranda, Else; Günther Sapunar, Germán; Pizarro, Nancy; Zanocco Loyola, Antonio (AMER CHEMICAL SOC, 2008-07-18)
      The photophysics and photochemistry of a series of naphthoxazinones have been studied using a combination of methods ranging from steady-state and time-resolved spectroscopic techniques to product analysis. The photophysics ...
    • Photosensitized generation of singlet molecular oxygen by aryloxazinones 
      Lemp Miranda, Else; Cañete, Alvaro; Günther Sapunar, Germán; Pizarro, Nancy; Zanocco Loyola, Antonio (ELSEVIER, 2008-09-25)
      The photophysical properties, the capacity to produce singlet molecular oxygen by sensitization and the photostability of a series of 20 aryloxazinones and one quinoxalinone have been evaluated using a combination of methods ...
    • Protective effect of boldo and tea infusions on the visible light-mediated pro-oxidant effects of vitamin ... 
      Silva, E.; Jopia, M.; Edwards, A.; Lemp Miranda, Else; Fuente, Julio de la; Lissi Gervaso, Eduardo (2002)
      The effect of Boldo and black tea infusions on the pro-oxidant effects of vitamin B-2, riboflavin (R-F), when exposed to the action of visible light was studied. The amounts of antioxidants present in Boldo and tea infusions ...
    • Solubilization of dodac small unilamellar vesicles by sucrose esters: A fluorescence study 
      Becerra,; De La Nuez,; Zanocco Loyola, Antonio; Lemp Miranda, Else; Günther Sapunar, Germán (Elsevier, 2006)
      A fluorescence method was employed to study the solubilizing interactions of several sucrose esters with Dioctadecyldimethylammonium chloride small unilamellar vesicles. In this paper we studied four different alkyl esters ...
    • Solubilization of lipid bilayers by myristyl sucrose ester: effect of cholesterol and phospholipid head group size 
      Toro, C.; Sánchez, S. A.; Zanocco Loyola, Antonio; Lemp Miranda, Else; Gratton, E.; Gunthera, G. (Elsevier, 2009-02)
      The solubilization of biological membranes by detergents has been used as amajor method for the isolation and purification of membrane proteins and other constituents. Considerable interest in this field has resulted ...
    • Sucrose Monoester Micelles Size Determined by Fluorescence Correlation Spectroscopy (FCS) 
      Sánchez, Susana A.; Gratton, Enrico; Zanocco Loyola, Antonio; Lemp Miranda, Else; Günther Sapunar, Germán (PUBLIC LIBRARY SCIENCE, 2011-12-28)
      One of the several uses of sucrose detergents, as well as other micelle forming detergents, is the solubilization of different membrane proteins. Accurate knowledge of the micelle properties, including size and shape, are ...
