Enhancement of the solubility of 5-fluorouracil through encapsulation within β-...
Machado, Mónica; Silva, Gabriela A.; Ferreira, Joana; Pinto, Luís Abegão; Ferreira, QuirinaThis journal is © The Royal Society of Chemistry.; 5-Fluorouracil (5-FU) is an antimetabolite agent used in chemotherapy and wound healing management, with low solubility and bioavailability. To overcome these challenges, this study explores the encapsulation of 5-FU within β-cyclodextrin (β-CD). The inclusion complex was prepared using the solubilization process, and its stability was evaluated under a variety...

Machado, Mónica; Oliveira, Alexandra M.L.; Silva, Gabriela A.; Bitoque, Diogo B.; Ferreira, Joana Tavares; Pinto, Luís Abegão; Ferreira, QuirinaFunding: This research was funded by Fundação para a Ciência e Tecnologia (FCT) through the projects iNOVA4Health, Translational Medicine program—UIDB/Multi/04462/2020; UIDB/50008/2020 and PTDC/CTM-REF/2679/2020.; Graphene is the material elected to study molecules and monolayers at the molecular scale due to its chemical stability and electrical properties. The invention of scanning tunneling microscopy has de...
Graphene oxide layer-by-layer films for sensors and devices
Assunção, Ivan C. C.; Sério, Susana; Ferreira, Quirina; Jones, Nykola C.; Hoffmann, Søren V.; Ribeiro, Paulo A.; Raposo, MariaLayer-by-layer films of poly (allylamine hydrochloride) (PAH) and graphene oxide (GO) were characterized, looking at growth with the number of bilayers, morphology, and electrical properties. The PAH/GO films revealed a linear increase in absorbance with the increase in the number of deposited bilayers, allowing the determination that 10.7 ± 0.1 mg m−2 of GO is adsorbed per unit of area of each bilayer. GO abso...
