    • Lipid-lipid interactions of Escherichia coli mimetic inner membrane at human physiological temperature 

      Hoyo Pérez, Javier; Torrent Burgués, Juan; Tzanov, Tzanko (2020-03-26)
      Article
      Open Access
      The current strategies to eradicate bacteria require that the antimicrobial agent either penetrate or disrupt the bacterial membrane. In Escherichia coli (E.coli) as a model of Gram-negative strains, the antimicrobials ...

      Burgos Fernández, Francisco Javier; Guaus Guerrero, Ester; Martínez, Cristina; Vilaseca Ricart, Meritxell (2019)
      Article
      Open Access
      The use of terahertz-based techniques has grown very fast since they are capable of performingevaluations at molecular level, being very suitable for the analysis of biological samples and bioma-terials such as those for ...
    • Antibacterial polyurethane foams with incorporated lignin-capped silver nanoparticles for chronic wound treatment 

      Morena Gatius, Ángela Gala; Ivanova, Kristina Dimitrova; Pérez Rafael, Silvia; Sánchez Soto, Miguel; Tzanov, Tzanko (2020-02-26)
      Article
      Open Access
      Lignin-capped silver nanoparticles were incorporated in situ into polyurethane foams during their polymerization to obtain multifunctional materials suitable for chronic wound dressing. Lignin with increased phenolic ...

    • Effect of lysozyme subphase and insertion on several lipid films 

      Torrent Burgués, Juan; Raju, Rekha (2019-06)
      Article
      Open Access
      The influence of proteins on lipid monolayers is a subject of biological interest. In this work the influence of lysozyme on lipid films of stearic acid, oleic acid, cholesterol, DPPC and POPC has been studied. The Langmuir ...
    • Poly(sulfobetaine methacrylate)/poly(ethylene glycole) hydrogels for chronic wounds management 

      Ruseva, Konstans; Ivanova, Kristina Dimitrova; Todorova, Katerina; Gabrashanska, Margarita; Hinojosa-Caballero, Dolores; Tzanov, Tzanko; Vassileva, Elena (Elsevier, 2019-05-14)
      Article
      Open Access
      Polyzwitterions (PZI) recently emerged as biomaterials with excellent bio- and haemo-compatibility, demonstrating lower protein adsorption on their surfaces even compared to the golden standard in the field – poly(ethylene ...
    • Action potential propagation: ion current or intramembrane electric field? 

      Martí Cabarrocas, Albert; Pérez González, Juan Jesús; Madrenas Boadas, Jordi (2018-01-22)
      Article
      Open Access
      The established action potential propagation mechanisms do not satisfactorily explain propagation on myelinated axons given the current knowledge of biological channels and membranes. The flow across ion channels presents ...
    • Effect of set up protocols on the accuracy of alchemical free energy calculation over a set of ACK1 inhibitors 

      Granadino, Jose Manuel; Mey, Antonia S. J. S.; Pérez González, Juan Jesús; Bosisio, Stefano; Rubio Martínez, Jaime; Michel, Julien (Public Library of Science (PLOS), 2019-03-01)
      Article
      Open Access
      Hit-to-lead virtual screening frequently relies on a cascade of computational methods that starts with rapid calculations applied to a large number of compounds and ends with more expensive computations restricted to a ...
    • Electrical evaluation of bacterial virulence factors using nanopores 

      Escosura Muñiz, Alfredo de la; Ivanova, Kristina Dimitrova; Tzanov, Tzanko (2019-03-19)
      Article
      Open Access
      In this work, we propose a novel methodology for electrical monitoring using nanoporous alumina membranes of virulence factors secreted by bacterial pathogens. Bacterial hyaluronidase (HYAL), which is produced by a number ...
