Extraction method plays critical role in antibacterial activity of propolis loaded hydrogels.
de Lima, Gabriel Goetten; de Souza, Ronaldo O,; Bozzi, Aline; Poplawska, Malgorzata A.; Devine, Declan M.; Nugent, Michael J. D. (Elsevier, 2016-03)Extracted propolis has been used for a long time as a remedy. However, if the release rate of propolis is not controlled, the efficacy is reduced. To overcome this issue, extracted propolis was added to a cryogel system. ... -
Investigation of the effects of orientation on freeze/thawed Polyvinyl alcohol hydrogel properties.
Chee, Bor Shin; de Lima, Gabriel Goetten; Devine, Declan M.; Nugent, Michael J. D. (Elsevier, 2018-12)Although hydrogels produced via freeze-thawing (F/T) technique have been thoroughly studied in literature, stretching hydrogels in between freeze-thawing cycles could change its properties and might be modulated for drug ... -
A novel pH‐sensitive ceramic‐hydrogel for biomedical applications.
de Lima, Gabriel Goetten; Campos, Lucas; Junqueira, Amanda; Devine, Declan; Nugent, Michael J. D. (Wiley, 2015-12)Innovations on the field of smart hydrogels are now being held with loads of advantages. With recent progress, smart polymers can now be used on the market for specific target/objectives desired on medicine. However, the ... -
Photopolymerization for filling porous ceramic matrix: improvement of mechanical properties and drug delivering behaviour.
Canillas, María; Geever, Tess; Vieira, Katilayne; Nugent, Michael J. D.; Killion, John; Devine, Declan M.; Rodriguez, Miguel A. (Wiley, 2019-04)This work presents the photopolymerisation of composite scaffolds where a prefabricated ceramic scaffold was impregnated with poly(ethylene) glycol dimethacrylate (PEGDMA) macromonomer solution. The PEGDMA solution penetrates ... -
The production of a novel poly(vinyl alcohol) hydrogel cryogenic spheres for immediate release using a droplet system.
de Lima, Gabriel Goetten; Chee, Bor Shin; Moritz, Vicente Froés; Cortese, Yvonne J.; Maghalhães, Washington L. E.; Devine, Declan M.; Nugent, Michael J. D. (IOP Science, 2019-06-05)Although freeze-thaw mechanism for producing crosslinked hydrogels is relatively easy and simple, it lacks sufficient integrity and support leading to modifications on its three-dimensional polymeric network arrangement ...
