The comfort properties of a textile cannot be dissociated from its function. Considering this premise, we evaluated the physical and mechanical performance of a previously developed cosmeto-textile composed of cotton/elastane, functionalized with bovine serum albumin (BSA) and BSA/silk fibroin (BSA/SF) nanoemulsions, encapsulating -tocopherol (vitamin E). The surface functionalization of cotton fabrics with the nanoemulsions was confirmed by fabric staining with Coomassie Brilliant Blue R250 and by FTIR-ATR. The comfort properties including wetting, stiffness, stretching, draping ability, electrical resistance, and air and vapor permeability were evaluated. The results revealed that the functionalization of cotton fabrics with the developed protein-based nanoemulsions did not disturb the comfort properties of the textile material nor its functionality. This gives a good indication of the potential of the developed breathable cosmeto-textile to be used in contact with the human body with acceptable performance., This study was supported by the Portuguese Foundation for Science and Technology (FCT) under the scope of the strategic funding of UIDB/04469/2020 unit and BioTecNorte operation (NORTE-01-0145-FEDER-000004) funded by European Regional Development Fund under the scope of Norte2020 - Programa Operacional Regional do Norte; Fundação para a Ciência e a Tecnologia [NORTE-01-0145-FEDER-000004, UIDB/04469/2020], info:eu-repo/semantics/publishedVersion

To improve and develop green adsorbent with high pollutant removal ability to produce clean water from wastewater, the surface of nanocomposite (zeolitic imidazolate framework (ZIF-8) as a metal-organic framework (MOF) with graphene oxide (GO) hybrid) was functionalized using 3-aminopropyl trimethoxy silane (APTMS). To identify and characterization the synthesized materials (ZIF-8, GO , ZG (ZIF-8/GO), and ZGA (ZIF-8/GO/APTMS)), Raman, FTIR, XRD, TGA and TEM analyzes were performed. Acid blue 92 (Ab92) dye was used as a contaminant to remove from the aqueous environment. Effective parameters on the adsorption process, such as the effect of contaminant concentration, dosage, contact time, and pH, were investigated. The results showed that Ab92 removal confirms the Langmuir isotherm and the pseudo-second-order kinetic. The maximum adsorption capacity for Ab92 dye was 371.8 mg/g. According to the results, ZGA nanocomposite is an acceptable adsorbent for removing Ab92 dye from the effluent.

In the present study, we coated cotton fabrics with protein-based nanoparticles containing vitamin E (-tocopherol) by the pad-cure method. Scanning electron microscopy, Fourier transform infra-red spectroscopy, and air permeability analysis of coated samples confirmed the fixation of the nanoparticles onto the fabrics surface. The antioxidant activity of the coated fabrics was evaluated by 2,2-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radicals reduction. Samples coated with nanoparticles containing the highest amount of encapsulated vitamin E (20% of the oil phase) showed the highest antioxidant activity. The protein-based coating was maintained for at least 10 washing cycles, demonstrating the reliability of the pad-cure method for the fixation of nanoparticles onto cotton surfaces. A methodology for nanoparticles release from the coated surfaces and their transfer to other substrates was demonstrated by the simple crock meter rubbing in the presence of sweat and protease. A high amount of material can be transferred and released to other substrates, such as textiles and skin, through the synergistic effect of sweat/protease and abrasion. An array of cosmetic and medical applications are possible with the developed coating and release methodology in which vitamin E would impart vital benefits as skin protection, anti-aging product, or skin moisturizer., This study was supported by the Portuguese Foundation for Science and Technology (FCT) under the scope of the strategic funding of UID/ BIO/04469/2013 unit and COMPETE 2020 (POCI-01-0145-FEDER006684) and BioTecNorte operation (NORTE-01-0145-FEDER000004) funded by the European Regional Development Fund under the scope of Norte2020 − Programa Operacional Regional do Norte.

Nanoparticles of bovine serum albumin (BSA) and silk fibroin (SF) with entrapped α-tocopherol were produced via ultrasonic emulsification. Populations with particle size of 200300 nm and highly negatively charged were obtained for all the tested formulations. Entrapment efficiencies of around 99% revealed the effective encapsulation of α-tocopherol into the produced nanoformulations. Generally, these nanodevices did not induce significant cytotoxicity to human skin keratinocytes for all the concentrations tested. The developed formulations showed free radical scavenging of ABTS.+ ability resulting from the synergistic effect between proteins in formulation and the entrapped tocopherol. Overall, the results contribute for the establishment of BSA:VO and BSA:SF:VO as biodegradable and non-toxic nanoformulations for the functionalization of textile devices and controlled delivery of tocopherol into the skin., This study was supported by the Portuguese Foundation for Science and Technology (FCT) under the scope of the strategic funding of UID/BIO/04469/2013 unit and COMPETE2020 (POCI-01-0145FEDER-006684) and BioTecNorte operation (NORTE-01-0145FEDER-000004) funded by European Regional Development Fund under the scope of Norte 2020-Programa Operacional Regional do Norte.
