      Article
      Open Access
      Bacterial cellulose (BC) has emerged as an attractive adsorptive material for antimicrobial agents due to its fine network structure, its large surface area, and its high porosity. In the present study, BC paper was first ...

    • Bacterial cellulose-chitosan paper with antimicrobial and antioxidant activities 

      Cabañas Romero, L. Verónica; Valls Vidal, Cristina; Valenzuela, Susana V.; Roncero Vivero, María Blanca; Javier Pastor, F.I.; Diaz Lucea, M. Pilar; Martínez Martínez, Josefina (2020-03-12)
      Article
      Open Access
      The production of paper-based bacterial cellulose-chitosan (BC-Ch) nanocomposites was accomplished following two different approaches. In the first, BC paper sheets were produced and then immersed in an aqueous solution ...

    • Nanofibrillar networks enable universal assembly of superstructured particle constructs 

      Mattos, Bruno D.; Tardy, Blaise L.; Greca, Luiz G.; Kämäräinen, Tero; Xiang, Wenchao; Cusola Aumedes, Oriol; Magalhães, Washington; Rojas, Orlando J. (2020-05-08)
      Article
      Open Access
      Superstructured colloidal materials exploit the synergies between components to develop new or enhanced functions. Cohesion is a primary requirement for scaling up these assemblies into bulk materials, and it has only been ...

    • Elucidating the chemical nature of laccase-modified alkyl gallates 

      Cusola Aumedes, Oriol; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Roncero Vivero, María Blanca (2020-06-12)
      Article
      Open Access
      In the first part of the present work, relevant findings concerning the laccase (Lacc) activation of alkyl gallates, and its implementation in developing hydrophobic properties on cellulose-based substrates are reported. ...

    • Bacterial cellulose matrices to develop enzymatically active paper 

      Buruaga Ramiro, Carolina; Valenzuela, Susana V.; Valls Vidal, Cristina; Roncero Vivero, María Blanca; Javier Pastor, F.I.; Diaz Lucea, M. Pilar; Martínez Martínez, Josefina (2020-01-31)
      Article
      Open Access
      This work studies the suitability of bacterial cellulose (BC) matrices to prepare enzymatically active nanocomposites, in a framework of more environmentally friendly methodologies. After BC production and purification, ...

    • Lignin particles for multifunctional membranes, antioxidative microfiltration, patterning and 3D structuring 

      Cusola Aumedes, Oriol; Rojas, Orlando J.; Roncero Vivero, María Blanca (2019-11-08)
      Article
      Open Access
      We introduce a new type of particle-based membrane based on the combination of lignin particles (LPs) and cellulose nanofibrils (CNF), the latter of which are introduced in small volume fractions to act as networking and ...

    • Laccase/TEMPO-mediated bacterial cellulose functionalization: production of paper-silver nanoparticles composite with antimicrobial activity 

      Morena Gatius, Ángela Gala; Roncero Vivero, María Blanca; Valenzuela, Susana V.; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Javier Pastor, F.I.; Diaz Lucea, M. Pilar; Martínez Martínez, Josefina (2019-01-01)
      Article
      Open Access
      Bacterial cellulose (BC) was functionalized applying the Laccase/TEMPO oxidative treatment, leading to a five-fold increase of the concentration of carboxyl groups. Paper produced with this cellulose showed improved ...
