    • Copper-polymer nanocomposites: An excellent and cost-effective biocide for use on antibacterial surfaces 

      Tamayo, Laura; Azócar, Manuel; Kogan Bocian, Marcelo; Riveros, Ana; Páez, Maritza (2016)
      The development of polymer nanocomposites with antimicrobial properties has been a key factor for controlling or inhibiting the growth of microorganisms and preventing foodborne diseases and nosocomial infections. Commercially ...
    • Gold nanoparticle-membrane interactions: Implications in biomedicine 

      Riveros, Ana; Dadlani, Komal; Salas, Edison; Caballero, Leonardo; Melo, Francisco; Kogan Bocian, Marcelo (American Scientific Publishers, 2013)
      There has been an increase in the research towards the use of nanoparticles as a promising tool for nanomedicine, from imagenology, drug and gene delivery, to phototherapy. Little is known regarding the interaction between ...
    • Hybrid biomaterials based on calcium carbonate and polyaniline nanoparticles for application in photothermal therapy 

      Neira Carrillo, Andrónico; Yslas, Edith; Yazmin Amar, Marini; Vásquez Quitral, Patricio; Sánchez, Marianela; Riveros, Ana; Yáñez, Diego; Cavallo, Pablo; Kogan Bocian, Marcelo; Acevedo, Diego (2016)
      Inorganic materials contain remarkable properties for drug delivery, such as a large surface area and nanoporous structure. Among these materials, CaCO3 microparticles (CMPs) exhibit a high encapsulation efficiency and ...
    • Hydrogen peroxide removes TRPM4 current desensitization conferring increased vulnerability to necrotic cell death 

      Simon, Felipe; Leiva Salcedo, Elías; Armisen Yáñez, Ricardo; Riveros, Ana; Cerda, Oscar; Varela, Diego; Eguiguren, Ana Luisa; Olivero, Pablo; Stutzin Schottlander, Andrés (2010)
      Necrosis is associated with an increase in plasma membrane permeability, cell swelling, and loss of membrane integrity with subsequent release of cytoplasmic constituents. Severe redox imbalance by overproduction of reactive ...
    • Non-selective cation channels and oxidative stress-induced cell swelling 

      Simon, Felipe; Varela, Diego; Riveros, Ana; Eguiguren, Ana Luisa; Stutzin Schottlander, Andrés (Society of Biology of Chile, 2002)
      Necrosis is considered as a non-specific form of cell death that induces tissue inflammation and is preceded by cell swelling. This increase in cell volume has been ascribed mainly to defective outward pumping of Na+ caused ...
    • Peptide multifunctionalized gold nanorods decrease toxicity of β-amyloid peptide in a Caenorhabditis elegans model of Alzheimer's disease 

      Morales-Zavala, Francisco; Arriagada, Hector; Hassan, Natalia; Velasco, Carolina; Riveros, Ana; Álvarez, Alejandra R.; Minniti, Alicia N.; Rojas-Silva, Ximena; Muñoz, Luis L.; Vasquez, Rodrigo; Rodriguez, Katherine; Sanchez-Navarro, Macarena; Giralt, Ernest; Araya, Ey (Elsevier Inc., 2017)
      © 2017 Elsevier Inc. The properties of nanometric materials make nanotechnology a promising platform for tackling problems of contemporary medicine. In this work, gold nanorods were synthetized and stabilized with polyethylene ...
    • Shell-isolated nanoparticle-enhanced fluorescence (SHINEF) of CdTe quantum dots 

      Ramírez Maureira, Mónica; Vargas Cortés, Víctor; Riveros, Ana; Goulet, Paul J.G.; Osorio Román, Igor (Elsevier, 2015)
      We report shell-isolated nanoparticle-enhanced fluorescence (SHINEF) of CdTe quantum dots. Enhanced spectra are obtained after Ag SHINs were spread onto homogenous CdTe quantum dot/polyelectrolyte layer-by-layer (LbL) ...
    • Stable Conjugates of Peptides with Gold Nanorods for Biomedical Applications with Reduced Effects on Cell Viability 

      Adura, Carolina; Guerrero, Simón; Salas, Edison; Medel, Luis; Riveros, Ana; Mena, Juan; Arbiol, Jordi; Albericio, Fernando; Giralt, Ernest; Kogan Bocian, Marcelo (American Chemical Society, 2013)
      Gold nanorods used in therapy and diagnosis must be nontoxic and stable in biological media and should be specific for the target. The complete combination of these three factors has hindered the use of gold nanorods ...
