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...
Layer-by-layer electrospun PCL/PVA mats loaded with nisin Z for enhanced diabet...
Tavares, Tânia; Pinho, Sonia L. C.; Delgado-Pujol, Ernesto J.; Begines, Belén; Alcudia, Ana; Silva, C.; Antunes, Joana C.; Felgueiras, Helena PradoDiabetic foot ulcers (DFUs) represent a significant clinical challenge due to impaired healing and high susceptibility to infections, underscoring the urgent need for multifunctional wound dressings. This study explores the potential of multilayered electrospun mats composed of polycaprolactone (PCL) and poly(vinyl alcohol) (PVA) engineered by a layer-by-layer (LbL) electrospun-based deposition, and functionali...
Glycine-Nitrate Process for the Elaboration of Eu3+-Doped Gd2O3 Bimodal Nanopar...
Goglio, Graziella; Kaur, Gaganpreet; Pinho, Sonia L. C.; Penin, Nicolas; Blandino, Alexia; Geraldes, Carlos F. G. C.; Garcia, AlainMonoclinic and cubic europium-doped Gd2O3 structures were selectively synthesized by the glycine-nitrate process by fine control of the synthesis temperature through the crucial fuel/oxidant ratio. The cubic phase is obtained under fuel-rich conditions, whereas stoichiometric conditions induce the simultaneous formation of cubic and monoclinic polymorphs. The samples were subjected to appropriate sintering to o...
