Abstract A series of poly(vinyl alcohol) (PVA) based liquid compositions with addition of zinc oxide, silver and copper nano‑ particles has been prepared. The compositions also contained other consistency-forming organic components. The physico-chemical properties of the products have been determined. Their pH and density have been assessed. Also, the size of nanoparticles has been defined with using a dynamic light scattering technique. The compositions were subjected to XRD, FT-IR and microscopic analysis as well. Thanks to the incorporation of both metal oxide and metallic nanoparticles, it was possible to enrich the products with antibacterial properties. Their inhibiting properties in the growth of microorganisms have been confirmed against both Gram-negative and Gram-positive strains such as E. coli, S. aureus and P. aeruginosa. Thanks to the ability for solidification, the compositions may be applied on a bacterially contaminated surface, and after destroying the microorganisms and its solidification, it may be peeled off along with the dead bacterial film. Keywords: Nanosilver, Nanocopper, Zinc oxide nanoparticles, Coating, Antibacterial effect Highlights • Homogeneous PVA-based compositions have been prepared. • Compositions contained among others zinc oxide, silver or copper nanoparticles. • Thanks to the nanoparticles, the products exhibited biocidal properties. • Biocidal effect was confirmed against E. coli, S. aureus and P. aeruginosa.

• It is possible to solidify compositions and detach the dead bacterial cells.
Introduction Nanotechnology is considered to be one of the most dynamically developing sciences; it allows the improvement of existing products, devices and technological solutions but also allows the creation of new ones by using materials with at least one dimension in the range of 1–100 nm [1]. The growing state of knowledge about nanomaterials and the development of research methods makes it possible to control the size and shape of the obtained nanoparticles, which in turn, gives the materials new, favourable physico-chemical properties. The greatest progress is manifested in areas such as medicine, food
