Application of near-infrared light responsive biomaterials for improving the wo...
Graça, Mariana F. P.; Moreira, André F.; Correia, I.J.Despite aiming to improve the healing process, the wound dressings that have been developed thus far still present high production costs, uncontrolled drug delivery, and are unable to fully re-establish all features of native skin. In this field, the development of light-responsive dressings has been emerging due to the possibility of controlling the delivery of therapeutic agents both in time and space. Moreov...
Dextran-Based Injectable Hydrogel Composites for Bone Regeneration
Alves, Patrícia; Simão, Ana Filipa; Graça, Mariana F. P.; Mariz, Marcos; Correia, I.J.; Ferreira, PaulaCurrently, bone infections caused by diseases or injuries are a major health issue. In addition, the conventional therapeutic approaches used to treat bone diseases or injuries present several drawbacks. In the area of tissue engineering, researchers have been developing new alternative therapeutic approaches, such as scaffolds, to promote the regeneration of injured tissues. Despite the advantages of these mat...
Chitin- and chitosan-based strategies in wound healing
Cabral, Cátia S. D.; Graça, Mariana F. P.; Moreira, André F.; Diogo, Duarte de Melo; Correia, I.J.Nowadays, chronic wounds are still a huge health problem with a high impact on the patients’ quality of life. In this way, the development of an ideal wound dressing is of utmost importance. To accomplish that, researchers have been using natural polymers to produce new types of dressings, that can activate/direct specific cellular responses, leading to an improved healing process. Among the natural polymers, c...
Reduced graphene oxide-enriched chitosan hydrogel/cellulose acetate-based nanof...
Graça, Mariana F. P.; Melo, Bruna L.; Sousa, Rita Lima; Ferreira, Paula; Moreira, André; Correia, I.J.Asymmetric wound dressings have captured researchers' attention due to their ability to reproduce the structural and functional properties of the skin layers. Furthermore, recent studies also report the benefits of using near infrared (NIR) radiation-activated photothermal therapies in treating infections and chronic wounds. Herein, a chitosan (CS) and reduced graphene oxide (rGO) hydrogel (CS_rGO) was combined...
Electrospun Asymmetric Membranes as Promising Wound Dressings: A Review
Graça, Mariana F. P.; de Melo-Diogo, Duarte; Correia, Ilídio J.; Moreira, André F.Despite all the efforts that have been done up to now, the currently available wound dressings are still unable to fully re-establish all the structural and functional properties of the native skin. To overcome this situation, researchers from the tissue engineering area have been developing new wound dressings (hydrogels, films, sponges, membranes) aiming to mimic all the features of native skin. Among them, a...

Hyaluronic acid - Based wound dressings: A review
Graça, Mariana F. P.; Miguel, Sónia P.; Cabral, Cátia S. D.; Correia, I.J.Hyaluronic acid (HA), a non-sulfated glycosaminoglycan (GAG), is a major component of skin extracellular matrix (ECM) and it is involved in the inflammatory response, angiogenesis, and tissue regeneration process. Due to the intrinsic properties of HA (such as biocompatibility, biodegradability and hydrophilic character), it has been used to produce different wound dressings, namely sponges, films, hydrogels, a...
