      Article
      Open Access
      Silver nanoparticles (AgNPs) have broad spectrum antibacterial activity, but their toxicity to human cells has raised concerns related to their use as disinfectants or coatings of medically relevant surfaces. To address ...

    • Antibiofilm poly(carboxybetaine methacrylate) hydrogels for chronic wounds dressings 

      Ruseva, Konstans; Ivanova, Kristina Dimitrova; Todorova, Katerina; Vladov, Ivelin; Nanev, Vesselin; Tzanov, Tzanko; Hinojosa-Caballero, Dolores; Argirova, Maya; Vassileva, Elena (Elsevier, 2020-04-12)
      Article
      Restricted access - publisher's policy
      The current study demonstrates the benefits of poly(carboxybetaine methacrylate) hydrogels in chronic wound healing. These hydrogels demonstrate high absorbing capacity upon swelling in salt solutions thus revealing great ...

    • 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 ...

    • Terahertz-based system for dehydration analysis of hydrogel contact lenses 

      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
