• Foodborne infections are an important global health problem due to their high prevalence and potential for severe complications. Bacterial contamination of meat during processing at the enterprise can be a source of foodborne infections. Polymeric coatings with antibacterial properties can be applied to prevent bacterial contamination. A composite coating based on fluoroplast and Ag O NPs can serve as such a coating. In present study, we, for the first time, created a composite coating based on fluoroplast and Ag O NPs. Using laser ablation in water, we obtained spherical Ag O NPs with an average size of 45 nm and a ζ-potential of -32 mV. The resulting Ag O NPs at concentrations of 0.001-0.1% were transferred into acetone and mixed with a fluoroplast-based varnish. The developed coating made it possible to completely eliminate damage to a Teflon cutting board. The fluoroplast/Ag O NP coating was free of defects and inhomogeneities at the nano level. The fluoroplast/Ag O NP composite increased the production of ROS (H O , OH radical), 8-oxogualnine in DNA in vitro, and long-lived active forms of proteins. The effect depended on the mass fraction of the added Ag O NPs. The 0.01-0.1% fluoroplast/NP Ag O coating exhibited excellent bacteriostatic and bactericidal properties against both Gram-positive and Gram-negative bacteria but did not affect the viability of eukaryotic cells. The developed PTFE/NP Ag O 0.01-0.1% coating can be used to protect cutting boards from bacterial contamination in the meat processing industry.
