    • Biomimetic quantum dot-labeled B16F10 murine melanoma cells as a tool to monitor early steps of lung ... 
      Díaz García, Víctor; Guerrero, Simón; Díaz Valdivia, Natalia; Lobos González, Lorena; Kogan Bocian, Marcelo; Pérez Donoso, José; Quest, Andrew F. G. (NLM (Medline), 2018)
      Background: Numerous studies have proposed the use of fluorescent semiconductor nanoparticles or quantum dots (QDs) as novel tools to label cells and tumors. However, QD applications are limited by their toxicity in ...
    • 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 ...
    • Quantum dot-based assay for Cu2+ quantification in bacterial cell culture 
      Durán Toro, V.; Gran Scheuch, A.; Órdenes Aenishanslins, N.; Monrás, J. P.; Saona, L. A.; Venegas, F. A.; Chasteen, T. G.; Bravo, D.; Pérez Donoso, José (Elsevier, 2014)
      A simple and sensitive method for quantification of nanomolar copper with a detection limit of 1.2 x 10-10 M and a linear range from 10-9 to 10-8 M is reported. For the most useful analytical concentration of quantum ...
