Sažetak
In daily life viruses and bacteria pose a serious threat to public health. Their structure allows them to bind on different surfaces and they can be spread by touching the contaminated surfaces. Due to remarkable characteristics and properties metal nanoparticles (NPs) are recognized as promising agents for battling viruses and bacteria [1, 2]. Currently, CuO and ZnO NPs are in research focus for antibacterial and antiviral applications. As microelements in the human body, they are both biocompatible and interesting for daily application. The overall aim of the research was to prepare CuO and ZnO NPs with different sizes and morphology and to determine their characteristics. As well as to use the prepared NPs for coating different surfaces (textile materials, Teflon and stainless steel) and to determine the change in the surface properties after the treatment. The NP synthesis was conducted in an aqueous solution, and the NP composition was determined by FTIR and PXRD analysis. The morphology of the NPs was determined with SEM while the NP surface charge was determined by a Particle charge detector. Contact angles and zeta potential of the textile, Teflon and stainless steel materials with and without nanoparticles were determined. The results showed that nanoparticles with different sizes and morphology (Fig 1) exhibit different surface properties and change the properties of treated surfaces and as well they showed promising antibacterial activity.
