Labelling composition, methods and uses thereof

The 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, ...

Physical properties of an antibacterial and antiviral woven cotton functionaliz...

[Excerpt] Introduction Wound infection is a critical factor that seriously hinders adequate healing preventing epithelialization and angiogenesis. This is particularly grievous and prevalent in burn and chronic wounds.

Antiviral properties of flame retardant bacterial nanocellulose modified with m...

Current COVID-19 pandemic has underscored the requirement of antiviral properties in a plethora of textile applications. These include textiles used in home areas prone to fire such as kitchens, windows and electronic panel areas, but also in the automotive industry such interior textiles and hood insulation pad covers. Therefore, this work describes the characterization of a fully sustainable textile: bacteria...

Antiviral properties of flame retardant bacterial nanocellulose modified with m...

[Excerpt] Bacterial nanocellulose (BNC) is a 100 % cellulose nano-nonwoven textile synthesized by bacteria, comprising impressive mechanical properties. Cellulosic materials require flame retardant finishing, thus to reduce flammability of BNC a zeolite mordenite (MOR) was incorporated in its nano structure, without any additives.

Distinct antimicrobial analysis to evaluate multi-component wound dressing perf...

Wound infection hinders adequate healing, being particularly grievous and prevalent in burn wounds and chronic wounds. Wound infection extends inflammation, preventing epithelialization and angiogenesis. Therefore, infection prolongs healing time, steeply increases treatment costs and degrades patients wellbeing. One successful strategy to control wound infection is to apply an active wound dressing, able to el...

Pretreatment of textiles through atmospheric plasma

There are several technologies available for the treatment of textile substrates. In a context where more environmentally and sustainable attitudes need to be adopted, industries must find technologically advanced solutions towards it, such as waterless technologies. An example is the atmospheric plasma, which allows the continuous and uniform pre-treatment of textile substrates, to make the next step – functio...

Sustainable identity through switchable fluorescence: smart textiles with rever...

[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...

Colour-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...

Multicomponent wound dressing

This works describes the antimicrobial (antibacterial and antiviral) performance of a multicomponent fabric for wound dressing. The fabric comprises a scaffold of plasma activated polyester (PES), enveloped in a matrix of chitosan (CH) containing silver nanoparticles (AgNPs) and the zeolite mordenite (MOR). The antimicrobial efficacy of the cumulative addition of each of these components was evaluated.
