Interaction of silver-lignin nanoparticles with mammalian mimetic membranes
(Frontiers Media SA, 2020-05-08)
Article
Open AccessSilver 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 ... -
Ionic liquids as biocompatible antibacterial agents: a case study on structure-related bioactivity on Escherichia coli
(American Chemical Society, 2022-10-19)
Article
Open AccessThe potential of ionic liquids (ILs) to be used as antimicrobial agents for biomedical applications has been hindered by the fact that most of them are cytotoxic toward mammalian cells. Understanding the mechanism of ... -
Layer-by-layer decorated nanoparticles with tunable antibacterial and antibiofilm properties against both gram-positive and gram-negative bacteria
(2018-01-09)
Article
Open Accessacteria-mediated diseases are a global healthcare concern due to the development and spread of antibiotic resistant strains. Cationic compounds are considered membrane active biocidal agents having a great potential to ... -
Lipid artificial tears at a mimetic ocular interface
(2021-08)
Article
Open AccessWe studied the behaviour of three lipid tear products, commercialised by the same brand, as Langmuir films at the air/liquid interface to simulate the ocular environment. No significant differences were observed in the ... -
Lipid-lipid interactions of Escherichia coli mimetic inner membrane at human physiological temperature
(2020-03-26)
Article
Open AccessThe 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 ... -
Metal-enzyme nanoaggregates eradicate both gram-positive and gram-negative bacteria and their biofilms
(2018-11-13)
Article
Open AccessTo palliate the appearance of antimicrobial resistance (AMR), the use of bactericidal agents acting differently than conventional antibiotics and the elimination of bacterial biofilm, are the two most promising strategies. ... -
Monogalactosyldiacylglycerol and digalactosyldiacylglycerol role, physical states, applications and biomimetic monolayer films
(2016-03-29)
Article
Open AccessThe relevance of biomimetic membranes using galactolipids has not been expressed in any extensive experimental study of these lipids. Thus, on the one hand, we present an in-depth article about the presence and role of ... -
Multifunctional enzymatically generated hydrogels for chronic wound application
(2017-04-19)
Article
Open AccessThe healing of chronic wounds requires intensive medical intervention at huge healthcare costs. Dressing materials should consider the multifactorial nature of these wounds comprising deleterious proteolytic and oxidative ... -
Multifunctional ZnO NPs-chitosan-gallic acid hybrid nanocoating to overcome contact lenses associated conditions and discomfort
(2019-02-13)
Article
Open AccessContact lenses (CL) provide visual correction but their use may also induce several adverse effects causative of discomfort and conditions that lead to stop or discontinue their use. Discomfort is mainly caused by insufficient ... -
Nanotransformation of vancomycin overcomes the intrinsic resistance of Gram-negative bacteria
(2017-04-10)
Article
Open AccessThe increased emergence of antibiotic-resistant bacteria is a growing public health concern, and although new drugs are constantly being sought, the pace of development is slow compared with the evolution and spread of ... -
Novel lignin-capped silver nanoparticles against multidrug resistant bacteria
(2021-05-04)
Article
Open AccessThe emergence of bacteria resistant to antibiotics and the resulting infections are increasingly becoming a public health issue. Multidrug-resistant (MDR) bacteria are responsible for infections leading to increased morbidity ... -
Organized molecular thin films for technological and biomimetic applications
(Campus de Terrassa de la UPC, 2013-06-13)
Conference report
Open Access -
Physical states and thermodynamic properties of model Gram-negative bacterial inner membranes
(2018-12-06)
Article
Open AccessNovel antimicrobial agents are focused to interact with the bacterial membrane whose lipid composition (number and position of unsaturations and lipid headgroup) is adapted according to environmental signals. The anticipation ... -
Quinones redox behaviour in supported lipid planar bilayers
(Universidad de Alcalá, 2010)
Part of book or chapter of book
Restricted access - author's decision -
Thylakoid membrane bioenergetics
(Elsevier, 2018-04-23)
Part of book or chapter of book
Restricted access - publisher's policyOxygenic photosynthesis is a unique and essential photochemical process in which solar energy is used to oxidize water and to form carbohydrates. In this process molecular oxygen is released as a by-product. Thylakoid ... -
Tuning ubiquinone position in biomimetic monolayer membranes
(2017-06-19)
Article
Open AccessArtificial lipid bilayers have been extensively studied as models that mimic natural membranes (biomimetic membranes). Several attempts of biomimetic membranes inserting ubiquinone (UQ) have been performed to enlighten ...
