Pozycja Natural ceramic nanoparticles ‒ layered aluminosilicates as an active phase of polymer nanocomposites and their potential application in medicine(Wydawnictwo Politechniki Łodzkiej, 2018-11-23) Stodolak-Zych, E.; Dzierzkowska, E.; Rapacz-Kmita, A."Developing knowledge in the field of nanotechnology and its potential medical applications in many cases may provide solutions that both patients and doctors expect. However, one should be aware that the application of nanotechnology entails the need to answer a number of bothering questions about the safety of using nanoparticles as well as nanomaterials based on them. The excess surface energy of materials at the nanometer scale, resulting from the strongly developed surface, can be used as a carrier of drugs, proteins, e.g. enzymes or antigens. Particularly interesting here are the naturally occurring layered aluminosilicates (e.g. smectites), whose variety of forms, availability, ease of extraction, as well as the repetition of purification and the possibility of chemical modification, allow the use as stand-alone nanoparticles, but also as fillers in the polymeric phase. The paper presents the possibilities of using aluminosilicate particles based on montmorillonite (MMT) and kaolinite (K) in biomedical applications."Pozycja Development of a plasma activated multifunctional polyester fabric using zinc oxide nanoparticles and citronella oil microcapsules(Wydawnictwo Politechniki Łódzkiej, 2022) Mehravani, Behnaz; Nicolau, Talita; Ribeiro, Ana Isabel; Parente, Joana F.; Sousa, Vânia I.; Tavares, Carlos J.; Padrão, Jorge; Zille, AndreaThere is a high demand for the development of textiles possessing multifunctional properties for outdoor, protective and health care applications. The coating of polyester (PES) textiles with metal nanoparticles and essential oils may act in a synergistic mode to obtain materials with improved antimicrobial and UV-protection properties. However, the lack of functional groups onto PES structure makes the adhesion of particles a difficult task. In this work, PES fabric was activated by dielectric barrier discharge (DBD) plasma treatment, and functionalized with zinc oxide nanoparticles (ZnO NPs) and poly (methyl methacrylate) (PMMA)-citronella microcapsules by dip-coating.Pozycja In-situ green synthesis of zinc oxide nanoparticles (ZnO NPs) onto the cotton fabrics by neem (azardirachta indica) leaf extract(Wydawnictwo Politechniki Łódzkiej, 2022) Javed, Asif; Wiener, Jakub; Saskova, Jana; Militky, JiriThis research work was carried out for the green in-situ synthesis of ZnO nanoparticles onto the 100% cotton fabric. Zinc nitrate hexahydrate [Zn(NO3)2.6H2O] was used as precursor and the Neem (Azardirachta Indica) leaf extract was used as reducing agent. Scanning electron microscopy (SEM) and X ray diffraction (XRD) were done to investigate the surface morphology and characteristics of developed samples. Moreover the ultraviolet protection factor (UPF), UVA blocking %age, UVB blocking %age, and antibacterial properties were examined. The SEM and XRD confirmed the deposition of ZnO NPs onto the fabric having crystalline structure. The evaluated samples showed very excellent results for, UPF rating, UVA blocking %age, UVB blocking %age, and antibacterial properties.
