Abstract
Public places such as swimming pools, saunas and jacuzzis are at high risk of developing microorganisms and are a potential source of disease. Above all, increased temperature and humidity favour this. A relatively new but effective way to combat microorganisms is to subject them to metal or metal oxide nanoparticles. The paper presents a method of obtaining nanocompositions for direct application at the place of occurrence of the microorganisms. The advantage of nanocompositions is that they can easily be removed from the infected surface in the form of a film containing dead organic matter. The article investigates the biocidal properties against common microorganisms such as Aspergillus niger and Candida albicans of nanocompositions containing silver nanoparticles and nanometric zinc oxide. The physicochemical properties of the nanocompositions were characterised and the antifungal properties of the preparations obtained determined using the suspension method. The results showed that the PVA-based compositions obtained were able effectively to inhibit the growth of the tested strains. Elongation of contact time between microorganism and nanoparticles which was changed from 5 to 60 min resulted in higher antimicrobial activity. It was manifested in reduced growth area. The same observation was made when the concentration of used nanoparticles was increased. When the concentration of nanosilver raised from 12.5 up to 200 ppm, the development of Aspergillus niger was slower. Increasing of zinc oxide nanoparticles concentration resulted in growth inhibition of Candida albicans strain.
