      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 ...
