    • Biomimetic, Mild Chemical Synthesis of CdTe-GSH Quantum Dots with Improved Biocompatibility 
      Pérez Donoso, José; Monrás, Juan P.; Bravo, Denisse; Aguirre, Adam; Quest, Andrew F. G.; Osorio Román, Igor; Aroca, Ricardo F.; Chasteen, Thomas G.; Vásquez, Claudio C. (2012)
      Multiple applications of nanotechnology, especially those involving highly fluorescent nanoparticles (NPs) or quantum dots (QDs) have stimulated the research to develop simple, rapid and environmentally friendly protocols ...
    • DNA, Cell Wall and General Oxidative Damage Underlie the Tellurite/Cefotaxime Synergistic Effect in Escherichia ... 
      Molina Quiroz, Roberto C.; Loyola, David E.; Muñoz Villagrán, Claudia; Quatrini, Raquel; Vásquez, Claudio C.; Pérez Donoso, José (PLoS ONE 8(11): e79499, 2013)
      The constant emergence of antibiotic multi-resistant pathogens is a concern worldwide. An alternative for bacterial treatment using nM concentrations of tellurite was recently proposed to boost antibiotic-toxicity and a ...
    • Microarray analysis of the Escherichia coli response to CdTe-GSH Quantum Dots: Understanding the bacterial ... 
      Monrás, Juan P.; Collao, Bernardo; Molina Quiroz, Roberto C.; Pradenas, Gonzalo A.; Saona, Luis A.; Durán Toro, Vicente; Órdenes Aenishanslins, Nicolás; Venegas, Felipe A.; Loyola, David E.; Bravo, Denisse; Calderón, Paulina F.; Calderón, Iván L.; Vásquez, Claudio C.; Chasteen, Thomas G.; López, Desiré A.; Pérez Donoso, José M. (BioMed Central, 2014)
      Background: Most semiconductor nanoparticles used in biomedical applications are made of heavy metals and involve synthetic methods that require organic solvents and high temperatures. This issue makes the development of ...
    • Monounsaturated Fatty Acids Are Substrates for Aldehyde Generation in Tellurite-Exposed Escherichia coli 
      Pradenas, Gonzalo A.; Díaz Vásquez, Waldo A.; Pérez Donoso, José; Vásquez, Claudio C. (Hindawi, 2013)
      Reactive oxygen species (ROS) damage macromolecules and cellular components in nearly all kinds of cells and often generate toxic intracellular byproducts. In this work, aldehyde generation derived from the Escherichia ...
