Profiling of oxygen in biofilms using individually addressable disk microelectrodes on a microfabricated needle
(2015-04-01)
Article
Accés obertA novel microelectrode array sensor was fabricated using MEMS technology on a needle, and then applied to real-time measurement of dissolved oxygen (DO) inside biofilms. The sensor consists of eleven gold disk microelectrodes ... -
Promising nanocomposites for food packaging based on cellulose-PCL films reinforced by using ZnO nanoparticles in an ionic liquid
(Elsevier, 2023-03)
Article
Accés obertThe fact that most composites consist of polluting synthetic materials has prompted a search for biodegradable replacements based on cellulose fibers and polycaprolactone as potential packaging materials. In this work, we ... -
Pseudomonas aeruginosa biofilms and their partners in crime
(2021-07)
Article
Accés obertPseudomonas aeruginosa biofilms and the capacity of the bacterium to coexist and interact with a broad range of microorganisms have a substantial clinical impact. This review focuses on the main traits of P. aeruginosa ... -
Quorum-quenching and matrix-degrading enzymes in multilayer coatings synergistically prevent bacterial biofilm formation on urinary catheters
(2015-12-02)
Article
Accés obertBacteria often colonize in-dwelling medical devices and grow as complex biofilm communities of cells embedded in a self-produced extracellular polymeric matrix, which increases their resistance to antibiotics and the host ... -
Reactive transport: a review of basic concepts with emphasis on biochemical processes
(2022-02)
Article
Accés obertReactive transport (RT) couples bio-geo-chemical reactions and transport. RT is important to understand numerous scientific questions and solve some engineering problems. RT is highly multidisciplinary, which hinders the ... -
Real-time multichannel system for the monitorization of biofilm formation based on quartz crystal resonators
(Universitat Politècnica de Catalunya, 2018-02)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorThe ability of certain microorganisms to bind to the surfaces of various materials (plastic, metal, ceramics) and develop complex structures such biofilm, is a critical health problem. The development of these structures ... -
Reducció de la dependència tèrmica de l'equip BIOPIEZO
(Universitat Politècnica de Catalunya, 2018-07)
Treball Final de Grau
Accés restringit per acord de confidencialitatThe main aim of the presented project is to lessen the temperature dependence of the BIOPIEZO measuring system towards the growth of bacterial film using quartz microbalances. To this end, an air-to-air refrigerator chamber ... -
Rheological properties of biofilms: steady and transient shear flow modeling
(2017)
Comunicació de congrés
Accés obert -
Role of soil biofilms in clogging and fate of pharmaceuticals: a laboratory-scale column experiment
(American Chemical Society, 2023-08)
Article
Accés obertContamination of groundwater with pharmaceutical active compounds (PhACs) increased over the last decades. Potential pathways of PhACs to groundwater include techniques such as irrigation, managed aquifer recharge, or bank ... -

Sonochemically engineered nano-enabled zinc oxide/amylase coatings prevent the occurrence of catheter-associated urinary tract infections
(Elsevier, 2021-10-26)
Article
Accés obertCatheter-associated urinary tract infections (CAUTIs), caused by biofilms, are the most frequent health-care associated infections. Novel antibiofilm coatings are needed to increase the urinary catheters' life-span, decrease ... -
Study of novel hybrid metal/enzyme nanoparticles coating for inhibition of bacterial biofilms on contact lenses
(Universitat Politècnica de Catalunya, 2023-06)
Treball Final de Grau
Accés obertL'ús de lents de contacte (LC) està molt estès actualment, tant per a la correcció d'errors refractius com amb fins estètics. Tot i els seus múltiples avantatges, un dels principals inconvenients de les LC és que són font ... -
Subsurface as a bioreactor : interaction between physical heterogeneity and microbial processes
(Universitat Politècnica de Catalunya, 2018-07-12)
Tesi
Accés obertInfiltration systems are water treatment technologies where water vertically percolates through porous media while several biogeochemical processes occur. Biofilms are the main responsible for those biogeochemical processes ... -
The role of biofilms in carbon steel corrosion processes
(Universitat Politècnica de Catalunya / University of Aberdeen, 2010)
Projecte/Treball Final de Carrera
Accés restringit per decisió de l'autorWhen a metal is introduced in seawater corrosion occurs on its surface. The corrosion on the metals, such as steel alloys, in determinates environments causes the apparition of gelatos biofilm formed just on the surface ... -
Valorization of paper waste sludge to produce films for packaging
