“…In literature NPs concentrations often are more than 1% [70,72], wherein the antibacterial activity of the obtained compositions is less than that of Ag 2 O NPs•BS [73]. Such composites have high antibacterial action against both Grampositive and Gram-negative bacteria, for example strains of Klebsiella, Listeria, Staphylococcus and Bacillus [74][75][76][77][78].…”

Microbial antibiotic resistance is an important global world health problem. Recently, an interest in nanoparticles (NPs) of silver oxides as compounds with antibacterial potential has significantly increased. From a practical point of view, composites of silver oxide NPs and biocompatible material are of interest. A borosiloxane (BS) can be used as one such material. A composite material combining BS and silver oxide NPs has been synthesized. Composites containing BS have adjustable viscoelastic properties. The silver oxide NPs synthesized by laser ablation have a size of ~65 nm (half-width 60 nm) and an elemental composition of Ag2O. The synthesized material exhibits strong bacteriostatic properties against E. coli at a concentration of nanoparticles of silver oxide more than 0.01%. The bacteriostatic effect depends on the silver oxide NPs concentration in the matrix. The BS/silver oxide NPs have no cytotoxic effect on a eukaryotic cell culture when the concentration of nanoparticles of silver oxide is less than 0.1%. The use of the resulting composite based on BS and silver oxide NPs as a reusable dry disinfectant is due to its low toxicity and bacteriostatic activity and its characteristics are not inferior to the medical alloy nitinol.

“…Similarly, Li et al investigated the potential of metallocene polyethylene containing AgNPs as coatings for medical devices. Antibacterial and silver ion release results showed excellent bactericidal properties against S. aureus and E. coli and a slow ion release for more than 30 days [ 155 ]. Another study by Lethongkam et al developed an endotracheal tube coating comprising a polyamide matrix and dispersed AgNPs.…”

The development of drug-resistant microorganisms has become a critical issue for modern medicine and drug discovery and development with severe socio-economic and ecological implications. Since standard and conventional treatment options are generally inefficient, leading to infection persistence and spreading, novel strategies are fundamentally necessary in order to avoid serious global health problems. In this regard, both metal and metal oxide nanoparticles (NPs) demonstrated increased effectiveness as nanobiocides due to intrinsic antimicrobial properties and as nanocarriers for antimicrobial drugs. Among them, gold, silver, copper, zinc oxide, titanium oxide, magnesium oxide, and iron oxide NPs are the most preferred, owing to their proven antimicrobial mechanisms and bio/cytocompatibility. Furthermore, inorganic NPs can be incorporated or attached to organic/inorganic films, thus broadening their application within implant or catheter coatings and wound dressings. In this context, this paper aims to provide an up-to-date overview of the most recent studies investigating inorganic NPs and their integration into composite films designed for antimicrobial therapies.

“…As alternative to the mixing methods for PM 0 C film making, coating of polymer films is also a good solution to avoid the problems related to the inner dispersion heterogeneity. For example, Lin Li et al (Li, Wang, & Zhu, 2018) (Table 1) prepared a AgNPs/MPE coating onto a PE film, resulting in an enhanced (>99%) antibacterial activity vs. E. coli and S. aureus. However, the close contact of the coating to the foodstuff may be posed as a drawback due to the related toxic effects as will be discussed in section 4.…”
