    • Assessment of the Nature Interactions of beta-Amyloid Protein by a Nanoprobe Method 

      Caballero, Leonardo; Mena, Juan; Morales Alvarez, Aurora; Kogan Bocian, Marcelo; Melo, Francisco (Amer Chemical Soc, 2015)
      We present a method based on atomic force microscopy (AFM) to assess the work of adhesion between the interfaces of gold AFM tips functionalized with three peptides derived from beta-sheet breaker LPFFD [CLPFFD-NH2 (i(0)) ...
    • Does bacterial elasticity affect adhesion to polymer fibers? 

      Tamayo Villarroel, Laura; Melo, Francisco; Caballero, Leonardo; Hamm, Eugenio; Díaz, M.; Leal, M. S.; Guiliani, Nicolás; Urzúa, M. D. (American Chemical Society, 2020)
      The factors governing bacterial adhesion to substrates with different topographies are still not fully identified. The present work seeks to elucidate for the first time and with quantitative data the roles of bacterial ...
    • 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 ...
    • Mechanical properties and electrical surface charges of microfibrillated cellulose/imidazole-modified polyketone composite membranes 

      González Cortes, Pablo; Araya Hermosilla, Rodrigo; Araya Hermosilla, Esteban; Acuña, Daniela; Mautner, Andreas; Caballero, Leonardo; Melo, Francisco; Moreno Villoslada, Ignacio; Picchioni, Francesco; Rolleri, Aldo; Quero, Franck (Elsevier, 2020)
      In the present work, microfibrillated cellulose (MFC) suspensions were produced by high-pressure homogenization and subsequently used to fabricate MFC membranes (C-1) by vacuum filtration followed by hot-pressing. A ...
    • Rosmarinic acid prevents fibrillization and diminishes vibrational modes associated to beta sheet in tau protein linked to Alzheimer’s disease 

      Cornejo, Alberto; Aguilar Sandoval, Felipe; Caballero, Leonardo; Machuca, Luis; Muñoz, Patricio; Caballero, Julio; Perry, George; Ardiles, Alejandro; Areche Medina, Carlos; Melo, Francisco (Taylor & Francis, 2017)
      Alzheimer’s disease is a common tauopathy where fibril formation and aggregates are the hallmark of the disease. Efforts targeting amyloid-b plaques have succeeded to remove plaques but failed in clinical trials to improve ...
    • Rosmarinic acid prevents fibrillization and diminishes vibrational modes associated to β sheet in tau protein linked to Alzheimer’s disease 

      Cornejo, Alberto; Aguilar Sandoval, Felipe; Caballero, Leonardo; Machuca, Luis; Jorquera Muñoz, Patricio; Caballero, Julio; Perry, George; Ardiles, Alejandro; Areche, Carlos; Melo, Francisco (Taylor and Francis Ltd, 2017)
      © 2017 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. Alzheimer’s disease is a common tauopathy where fibril formation and aggregates are the hallmark of the disease. Efforts targeting ...
    • Stress transfer and matrix-cohesive fracture mechanism in microfibrillated cellulose-gelatin nanocomposite films 

      Quero, Franck; Padilla, Cristina; Campos, Vanessa; Luengo, Jorge; Caballero, Leonardo; Melo, Francisco; Li, Qiang; Eichhorn, Stephen J.; Enrione, Javier (Elsevier, 2018-09)
      Microfibrillated cellulose (MFC) obtained from eucalyptus was embedded in gelatin from two sources; namely bovine and salmon gelatin. Raman spectroscopy revealed that stress is transferred more efficiently from bovine ...
