Pluronic® F127 Hydrogel Containing Silver Nanoparticles in Skin Burn Regenerati...
Francisco, Pedro; Neves Amaral, Mariana; Neves, Afonso; Ferreira-Gonçalves, Tânia; Viana, Ana S.; Catarino, José; Faísca, Pedro; Simões, SandraPresently, skin burns are considered one of the main public health problems and lack therapeutic options. In recent years, silver nanoparticles (AgNPs) have been widely studied, playing an increasingly important role in wound healing due to their antibacterial activity. This work is focused on the production and characterization of AgNPs loaded in a Pluronic® F127 hydrogel, as well as assessing its antimicrobia...
Exploring the potential of using Marine-Derived Ingredients: From the extractio...
Costa, João Pedro; L, Custódio; Reis, Catarina PintoThe growing understanding and knowledge of the potential of marine species, as well as the application of “blue biotechnology” have been motivating new innovative solutions in cosmetics. It is widely noted that that marine species are important sources of compounds with several biological activities that are yet to be discovered. This review explores various biological properties of marine-derived molecules and...
Marine natural products as innovative cosmetic ingredients
Fonseca, Sara; Amaral, Mariana Neves; Reis, Catarina Pinto; L, CustódioOver the course of the last 20 years, numerous studies have identified the benefits of an array of marine natural ingredients for cosmetic purposes, as they present unique characteristics not found in terrestrial organisms. Consequently, several marine-based ingredients and bioactive compounds are under development, used or considered for skin care and cosmetics. Despite the multitude of cosmetics based on mari...
Biological Thermal Performance of Organic and Inorganic Aerogels as Patches for...
Ferreira-Gonçalves, Tânia; Iglesias-Mejuto, Ana; Linhares, Teresa; Coelho, João M. P.; Vieira, Pedro; Faísca, Pedro; Catarino, José; Ferreira, DavidAerogels are materials with unique properties, among which are low density and thermal conductivity. They are also known for their exquisite biocompatibility and biodegradability. All these features make them attractive for biomedical applications, such as their potential use in photothermal therapy (PTT). This technique is, yet, still associated with undesirable effects on surrounding tissues which emphasizes ...
The Role of Rosmarinic Acid on the Bioproduction of Gold Nanoparticles as Part ...
Ferreira-Gonçalves, Tânia; Gaspar, Maria Manuela; Coelho, João M. P.; Marques, Vanda; Viana, Ana S.; Ascensão, Lia; Carvalho, LinaBreast cancer is a high-burden malignancy for society, whose impact boosts a continuous search for novel diagnostic and therapeutic tools. Among the recent therapeutic approaches, photothermal therapy (PTT), which causes tumor cell death by hyperthermia after being irradiated with a light source, represents a high-potential strategy. Furthermore, the effectiveness of PTT can be improved by combining near infrar...

Gold-Based Nanoplataform for the Treatment of Anaplastic Thyroid Carcinoma: A S...
Amaral, Mariana; Charmier, Adília J.; Afonso, Ricardo A.; Catarino, José; Faísca, Pedro; Carvalho, Lina; Ascensão, Lia; Coelho, João M. P.Anaplastic thyroid carcinoma (ATC) is a very rare subtype of thyroid carcinoma and one of the most lethal malignancies. Poor prognosis is mainly associated with its undifferentiated nature, inoperability, and failing to respond to the typically used therapies for thyroid cancer. Photothermal Therapy (PTT) entails using light to increase tissues’ temperature, leading to hyperthermia-mediated cell death. Tumours ...
Safety and efficacy assessment of aerogels for biomedical applications
Ferreira-Gonçalves, Tânia; Constantin, Carolina; Neagu, Monica; Reis, Catarina Pinto; Sabri, Firouzeh; Simón-Vázquez, RosanaThe unique physicochemical properties of aerogels have made them an attractive class of materials for biomedical applications such as drug delivery, regenerative medicine, and wound healing. Their low density, high porosity, and ability to regulate the pore structure makes aerogels ideal nano/micro-structures for loading of drugs and active biomolecules. As a result of this, the number of in vitro and in vivo s...
