In this paper, the experimental studies are concerned with the effect of the synthesis parameters on the formation of monometallic Ag and Cu nanoparticles (NPs). We consider the synthesis strategies verification for the bimetallic core-shell and alloy particles preparation. It was successfully obtained by chemical reduction method. The obtained colloidal solution is characterized by the transmission electron microscopy (TEM) with energy-dispersive X-ray spectroscopy (EDX) data, UV-Vis spectra, particle size distribution, and zeta potential. This work presents a comprehensive overview of experimental studies of the most stable colloidal solutions to impregnate fabrics that will exhibit a bactericidal and fungicidal activity against Candida albicans, Escherichia coli, and Staphylococcus aureus.

Abstract.

We reported a preparation and characterization of five kinds of impregnation solutions, containing Ag/Cu in the form of bimetallic nanoparticles (alloy and core-shell) as well as ionic species. The cotton-polyester textiles were successfully impregnated during the washing and ironing process by as-prepared solutions to have antibacterial and antifungal properties against to Escherichia coli, Staphylococcus aureus, and Candida albicans. Moreover, we have reported the effect of type of the fabric used and number of washing/impregnation cycles (in a laboratory scale) on the bactericidal and fungicidal activity of obtained textiles. The results indicated that all tested samples after 5, 10, 15, and 20 washing/impregnated cycles exhibited an antimicrobial activity. The antifungal tests showed that only textile impregnated with solutions containing Ag+/Cu2+ and Ag NPs/Cu2+exhibited a strong inhibition of fungi growth of the after 5 (99.99%) and 15 (100%) washing/impregnation cycles, respectively.

The problem of nosocomial infections is nothing new. In places, where people, The problem of nosocomial infections is nothing new. In places, where people, whose immune system is weakened, are gathered and subjected to various kinds of treatments, the risk of infection increases considerably. The use of textiles with biocidal finishing, which contains nanoAg and nanoCu, may give an additional protection against nosocominal infections. This article presents the latest information regarding various methods for synthesis, impregnation and immobilization of antibacterial coatings. It also describes the textile biocidal activity depending on the active agents applied and the type of textile used. The textile biocidal properties obtained by the described methods were systematically lost. Therefore, at the end of the article a method, which enables their constant renewing is presented. whose immune system is weakened, are gathered and subjected to various kinds of treatments, the risk of infection increases considerably. The use of textiles with biocidal finishing, which contains nanoAg and nanoCu, may give an additional protection against nosocominal infections.
