3D-printed polymer-infiltrated ceramic network with antibacterial biobased silver nanoparticles
(American Chemical Society, 2022-01-01)
Article
Open AccessThis work aimed at the antimicrobial functionalization of 3D-printed polymer-infiltrated biomimetic ceramic networks (PICN). The antimicrobial properties of the polymer-ceramic composites were achieved by coating them with ... -
Antibacterial lignin-based nanoparticles and their use in composite materials
(Royal Society of Chemistry (RSC), 2022-10-11)
Article
Open AccessLignin, one of the most abundant biopolymers on earth, has been traditionally considered a low-value by-product of the pulp and paper industries. This renewable raw material, besides being a source of valuable molecules ... -
Antibacterial polyurethane foams with incorporated lignin-capped silver nanoparticles for chronic wound treatment
(2020-02-26)
Article
Open AccessLignin-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 ... -
Antibacterial properties and mechanisms of action of sonoenzymatically synthesized lignin-based nanoparticles
(2022-08-12)
Article
Open AccessIn recent years, lignin has drawn increasing attention for different applications due to its intrinsic antibacterial and antioxidant properties, coupled with biodegradability and biocompatibility. However, chemical ... -

Enzymatically built nanoenabled antimicrobial coating on urinary catheters
(2024-07-23)
Article
Open AccessCatheter-associated urinary tract infections represent a major share of nosocomial infections, and are associated with longer periods of hospitalization and a huge financial burden. Currently, there are only a handful of ... -
Hybrid tellurium-lignin nanoparticles with enhanced antibacterial properties
(2021-04-07)
Article
Open AccessThe surge of antibiotic-resistant bacteria is leading to the loss of antibiotic treatment effectiveness, resulting in prolonged infections and even death. Against this healthcare threat, antimicrobial nanoparticles that ... -
Influence of enzymatically hydrophobized hemp protein on morphology and mechanical properties of bio-based polyurethane and epoxy foams
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-31)
Article
Open AccessBiomass fillers offer the possibility to modify the mechanical properties of foams, increasing their cost-effectiveness and reducing their carbon footprint. In this study, bio-based PU (soft, open cells for the automotive ... -
Laccase/TEMPO-mediated bacterial cellulose functionalization: production of paper-silver nanoparticles composite with antimicrobial activity
(2019-01-01)
Article
Open AccessBacterial 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 ... -
Lignin-based nanoparticles as both structural and active elements in self-assembling and self-healing multifunctional hydrogels for chronic wound management
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-11-30)
Article
Open AccessEfficient wound healing is feasible when the dressing materials simultaneously target multiple factors causing wound chronicity, such as deleterious proteolytic and oxidative enzymes and bacterial infection. Herein, entirely ... -
Lingnin-based nanoparticles with antibacterial properties and their nanocomposite materials for wound healing
(Universitat Politècnica de Catalunya, 2023-03-10)
Doctoral thesis
Open Access(English) Lignocellulosic biomass is an abundant renewable resource considered a suitable carbon raw material for the synthesis of chemicals and as an alternative to fossil fuels energy supply source. Cellulose, hemicellulose, ... -
Microbial cellulose from a komagataeibacter intermedius strain isolated from commercial wine vinegar
(2019-02-21)
Article
Open AccessIn this study a new bacterial cellulose (BC) producer isolated from commercial vinegar is identified as Komagataeibacter intermedius JF2 based on the examination of general taxonomical characteristics, 16S rDNA sequence ... -
Rigid composite bio-based polyurethane foams: from synthesis to LCA analysis
(Elsevier, 2023-01)
Article
Restricted access - publisher's policyOur current industrial ammonia cycle is far from being sustainable – while intense energy is required to produce ammonia – almost half of it ends up in wastewater treatment plants (WWTPs) where is finally transformed and ...
