Labelling composition, methods and uses thereof
Aguiar, Tatiana Quinta; Oliveira, Juliana; Barros, Ana Rita; Bouça, Verónica; Ramada, David; Freitas, Ana Isabel; Domingues, LucíliaThe present disclosure relates to a labelled article comprising a substrate selected from a list consisting of at least one of the following substrates: paper, cork, leather, yarns, threads, textiles, fabrics, a particle, or combinations thereof; a reversibly switchable fluorescent peptide; and a binder peptide, preferably more than one binder, wherein the binder binds the fluorescent peptide to the substrate, ...
Design of new hydrolyzed collagen-modified magnetic nanoparticles to capture pa...
Sande, Maria Georgina; Roque, Lúcia; Braga, Adelaide Correia; Marques, Márcia; Ferreira, Débora Carina Gonçalves Abreu; Saragliadis, AthanasiosEnrichment and diagnosis tools for pathogens currently available are time consuming, thus the development of fast and highly sensitive alternatives is desirable. In this study, a novel approach was described that enables selective capture of bacteria expressing hydrolyzed collagen-binding adhesins with hydrolyzed collagen-coated magnetic nanoparticles (MNPs). This platform could be useful to shorten the time ne...
Sustainable identity through switchable fluorescence: smart textiles with rever...
Barros, Ana; Ramada, David; Bouça, Verónica; Oliveira, Juliana; Freitas, Ana Isabel; Domingues, Lucília; Aguiar, Tatiana Quinta[Excerpt] Colour-changing materials with con - trollable properties obtained by low cost and biotechnological means are highly desirable for smart innovative products and applications such as anti-counterfeiting and security printing. Protein-based nanotechno - logy is an ever-growing research field due to the versatility and adap - tability of these biomolecule building blocks and the innovative functiona - li...
Innovative eco-sustainable photocontrolable and reversibly photoswitchable fluo...
Oliveira, Juliana; Bouça, Verónica; Barros, Ana; Ramada, David; Freitas, Ana Isabel; Domingues, Lucília; Aguiar, Tatiana QuintaColour-changing materials with controllable properties are highly desirable for technical, smart innovative products. Current developments commonly incorporate photo/thermochromic inks based on molecules obtained by non-sustainable petroleum based sources that do not allow controlled light-driven switching between colors. To overcome these limitations, our project explores the development of new eco-sustainable...

Bouça, Verónica; Oliveira, Juliana; Barros, Ana; Ramada, David; Coelho, Lorena; Freitas, Ana Isabel; Romão, João; Domingues, LucíliaColor-changing materials with controllable photoswitching properties are highly desirable for technical and smart textile products. In the quest for innovative light-responsive textiles, many efforts have been made to develop materials that can be easily incorporated into fibers and/or fabrics by conventional dyeing, printing or coating processes. Current developments commonly incorporate photochromic inks that...
Collagen-coated magnetic nanoparticles to capture pathogens from biological sam...
Sande, Maria; Roque, Lúcia; Marques, Márcia; Ferreira, Débora; Rodrigues, Joana Lúcia Lima Correia; Braga, Adelaide; Ramada, David; Silva, C.Conventional methods of diagnosing bacterial infections such as microbial culture and molecular techniques, while highly sensitive, rely on expensive equipment and highly skilled operators. There is a need for affordable and portable diagnostic systems which are simple to operate while preserving reliability. Pre-enrichment of bacteria present in a sample coupled with subsequent bacterial identification steps c...
