Elastic bands antimicrobial functionalization
Ferreira, Ana Francisca; Fernandes, Rui Daniel Vilaça; Vieira, Bárbara Marques; Peixoto, Joaquim Jorge Gomes; Felgueiras, Helena Prado; Zille, AndreaSustainability of textile products encompasses the extension of their useful life period during which they adequately serve their intended purpose. Antimicrobial finishings can prevent microbial damage and extend textile lifespan. Even though the functionalization and characterization processes have been thoroughly described for woven, knitted and non-woven textiles, there is a lack of information regarding ela...
Pioneering wound care solutions: triaxial wet-spun fibers with bioactive agents...
Miranda, Catarina Alexandra Fortuna Santos; Marinho, Elina Margarida Ribeiro; Rocha, Diana; Silva, C.; Silva, Maria Manuela; Schlapp-Hackl, IngeFiber-based constructs have been produced as an alternative to conventional dressings for the treatment of chronic wounds (CWs), showing good tenability, high surface area and regulable porosity. A commonly used technique for processing such dressings is wet-spinning, which involves precipitating a polymer solution into a coagulation bath containing a non-solvent of that polymer. This process produces fibers wi...
Pioneering wound care solutions: triaxial wet-spun fibers with bioactive agents...
Miranda, Catarina Alexandra Fortuna Santos; Silva, Ana Francisca Gomes da; Evenou, Camille; Lamartine, Jérôme; Fromy, BerengereThe incidence of bacterial infections associated with chronic wounds (CWs) has increased in recent years. Thus, a triaxial wet-spun fibrous system (containing three layers) was produced for CW healing. The triaxial fibers were loaded with cinnamon leaf oil (CLO), endowed with high antibacterial, antioxidant and anti-inflammatory features, and an antimicrobial peptide alaninealanineprolinevaline (AAPV) capable o...
Polycaprolactone/sodium alginate coaxial wetspun fibers modified with carbon na...
Marinho, Elina Margarida Ribeiro; Silva, Beatriz M.; Miranda, Catarina Alexandra Fortuna Santos; Pinho, Sonia L. C.; Felgueiras, Helena PradoChronic wounds (CWs) are a significant public health concern and affect 1–2% of the world’s population. They are responsible for high morbidity and mortality rates. Bacterial infections caused by Staphylococcus aureus and Pseudomonas aeruginosa are very common in CWs and prevent normal wound healing steps from taking place. Carbon nanofibers (CNFs) have attracted interest due to their inherent antibacterial and...
Ion-exchanged zeolite as a hybrid system: Fluoxetine removal and antibacterial ...
Demiti, Gabriela Maria Matos; Homem, Natália Cândido; Felgueiras, Helena Prado; Ribeiro, Anna Carla; de Abreu Filho, Benício AlvesThe increasing consumption of antidepressants, aggravated by the coronavirus disease 2019 (COVID-19) pandemic, has resulted in the detection of compounds such as fluoxetine in drinking water. This substance is highly toxic to aquatic organisms and has the potential for bioaccumulation in aquatic environments. This study evaluated the effects of modifying natural zeolites through ion exchange to enhance their ad...
Lyocell/silver knitted fabrics for prospective diabetic foot ulcers treatment: ...
Tavares, Tânia Daniela Eugénio; Ribeiro, Artur; Bengoechea, Carlos; Rocha, Diana; Alcudia, Ana; Begines, Belén; Silva, C.; Antunes, Joana Isabel CostaDiabetic foot ulcers (DFUs) are a serious complication of diabetes, often resulting in infections and further health deterioration. Thus, the development of an approach combining different therapies in just one formulation to treat DFUs remains very challenging. Silver-plated polyamide fibers offer antimicrobial properties, while lyocell provides biodegradability, biocompatibility and moisture management abilit...
Development of Co-Axial fibres composed of CA (Mn 50,000) and PEGs (600 and 100...
Costa, Manuel F. M.; Carneiro, Joaquim A. O.; Hammes, Nathalia; Monteiro, José; Rocha Segundo, Iran Gomes da; Felgueiras, Helena PradoRapid urbanisation and industrialisation have intensified the Urban Heat Is-land (UHI) effect, significantly increasing energy demand for thermal comfort. Urban buildings consume considerable energy throughout the year, which can be reduced by incorporating Phase Change Materials (PCMs) into building materials. PCMs effectively regulate temperature by storing and releasing heat as latent heat during phase trans...
Circular economy practices in fashion design education: the first phase of a ca...
Moreira, Sofia; Felgueiras, Helena Prado; Marques, António DinisWith the growing significance of the circular economy (CE) agenda in the fashion industry and, consequently, in fashion design education, this work introduces the initial phase of a case study that aims to ascertain whether CE principles and sustainability are part of the curriculum and pedagogical approaches employed by educators in the Fashion Design Technician course (FDTC) (level 4, National Qualifications ...
Colourful protection: Challenges and perspectives of antibacterial pigments ext...
Gomes, Micaela; Felgueiras, Helena Prado; Leite, Barbara R.; Soares, Graça M. B.Bacterial pigments have gained significant attention across multiple industries due to their natural hues and unique functional properties. Beyond coloration, some of these pigments exhibit antibacterial activity, making them particularly valuable in the textile industry as sustainable alternatives to synthetic antimicrobial treatments. Bacteria produce a vast array of pigments through diverse biosynthetic path...

Ribeiro, Ana R. M.; Oliveira, Bruna A. S.; Barbosa, Ana Isabel; Seabra, Catarina L.; Reis, Salette; Felgueiras, Helena PradoRecently, biomedical engineering has seen significant advancements in nanomaterial-based scaffolds for tissue engineering and wound healing. Incorporating halochromic properties within these scaffolds has garnered substantial interest due to their real-time monitoring abilities for accessing tissue growth and regeneration. This review presents a comprehensive analysis of recent advancements in nanomaterial-base...
