Smart textiles have become a promising area of research for heating applications. Coatings with nanomaterials allow the introduction different functionalities, enabling doped to be used in sensing and These coatings were made on piece woven cotton fabric through screen printing, number layers. To prepare paste, such as graphene nanoplatelets (GNPs) multiwall carbon nanotubes (CNTs) added polyurethane-based polymeric resin, various concentrations. The electrical conductivity obtained samples...
Silk fibroin is a biobased material with excellent biocompatibility and mechanical properties, but its use in bioelectronics hampered by the difficult dissolution low intrinsic conductivity. Some ionic liquids are known to dissolve removed after processing. However, can cooperatively give rise functional materials, there untapped opportunities this combination. The of fibroin, followed gelation, designer from imidazolium chloride family varied alkyl chain lengths (2–10 carbons) shown here....
The development of advanced facemasks stands out as a paramount priority in enhancing healthcare preparedness. In this work, different polypropylene non-woven fabrics (NWF) were characterised regarding their structural, physicochemical and comfort-related properties. selected NWF for the intermediate layer was functionalised with zinc oxide nanoparticles (ZnO NPs) 0.3 1.2wt% using three methods: electrospinning, dip-pad-dry exhaustion. After confirmation ZnO NP content distribution within...
Pressure injuries (PIs) are a major public health problem and can be used as quality-of-care indicators. An incipient development in the field of medical devices takes form Smart Health Textiles, which possess innovative properties such thermoregulation, sensing, antibacterial control. This protocol aims to describe process for new type smart clothing individuals with reduced mobility and/or who bedridden order prevent PIs. paper's main purpose is present eight phases project, each...
We report on the biocatalytic activation of a self-assembling (unprotected) tripeptide to stabilize oil-in-water emulsions on-demand. This is achieved by conversion phosphorylated precursor into hydrogelator using alkaline phosphatase (AP) as trigger. The rate conversion, controlled amount enzyme used, shown play key role in dictating morphology nanofibrous networks produced. When these amphiphilic tripeptides are used biphasic mixtures, nanofibers self-assemble not only at aqueous/organic...
We report on-demand formation of emulsions stabilised by interfacial nanoscale networks. These are formed through biocatalytic dephosphorylation and self-assembly Fmoc(9-fluorenylmethoxycarbonyl)dipeptide amphiphiles in aqueous/organic mixtures. This is achieved using alkaline phosphatase which transforms surfactant-like phosphorylated precursors into self-assembling aromatic peptide (Fmoc-tyrosine-leucine, Fmoc-YL) that form nanofibrous In biphasic organic/aqueous systems, these networks...
In this work, we describe the development of a computational screening approach for tripeptide-dipeptide co-assembly. Studies are carried out both in water and oil–water mixtures, to evaluate possible candidates that give rise hydrogels or more stable emulsions, respectively, through nanofibre formation. The results design rules identification promising systems numerous types soft materials. possibility achieving innovative functional materials co-assembly tripeptides dipeptides is studied....
Although the force/pressure applied onto a textile substrate through uniaxial compression is constant and independent of yarn direction, it should be noted that such mechanical action causes geometric change in substrate, which can identified by reduction its lateral thickness. Therefore, objective this study was to investigate influence fabric orientation on both knitted woven pressure sensors, order generate knowledge for better design process during piezoresistive sensor development. For...
There is significant interest in the use of unmodified self-assembling peptides as building blocks for functional, supramolecular biomaterials. Recently, dynamic peptide libraries (DPLs) have been proposed to select materials from dynamically exchanging mixtures dipeptide inputs presence a nonspecific protease enzyme, where sequences are selected and amplified based on their tendencies. It was shown that results DPL mixed (e.g. starting mixture dileucine, L2, diphenylalanine, F2) did not...
Reflectins are a family of intrinsically disordered proteins involved in cephalopod camouflage, making them an interesting source for bioinspired optical materials. Understanding reflectin assembly into higher-order structures by standard biophysical methods enables the rational design new materials, but it is difficult due to their low solubility. To address this challenge, we aim understand molecular self-assembly mechanism reflectin's basic unit-the protopeptide sequence YMDMSGYQ-as means...
We demonstrate phage-display screening on self-assembled ligands that enables the identification of oligopeptides selectively bind dynamic supramolecular targets over their unassembled counterparts. The concept is demonstrated through panning a oligopeptide library against tyrosine-phosphate using 9-fluorenylmethoxycarbonyl-phenylalanine-tyrosine-phosphate (Fmoc-FpY) micellar aggregates as targets. 14 selected peptides showed no sequence consensus but were enriched in cationic and proline...
