Abstract

Background: Antibacterial materials are of high importance for medicine, food production and conservation. Among these materials, polymer films with metals nanoparticles (NPs) are of considerable attention for many practical applications.
Results: The paper describes a novel approach for the formation of bactericidal media which are represented by thin polymer films (polystyrene in the current case), produced by spin-coating, with Ti and Cu NPs deposited from cluster beams. Ti NPs are treated in three different ways in order to study different approaches for oxidation and, thus, efficiency in formation of the particles with semiconducting properties required for catalysis of reactive oxygen species. Cu NPs are used as deposited. Partial NP embedding into polystyrene is realised in controllable manner using thermal annealing in order to improve surface adhesion and make the particles resistant against wash out. The formed composite films with TiOx and Cu species are tested as bactericidal media using E.coli bacteria as model microorganisms.
Conclusion: The obtained results show considerable efficiency in destroying the bacteria and good possibility of multiple re-use of the same composite films making the suggested approach attractive for the cases requiring reusable polymer-based antibacterial media.
