Metal nanoparticles exhibit unique properties that are highly appreciated in many novel-material applications, e.g., sensors and antibacterial coatings. However, low adherence of nanoparticles to surfaces limits their practical application. Therefore, the nanoparticles are often incorporated into a matrix, i.e., thin-film, which improves their attachment to a surface. Nevertheless, the functionality of nanoparticles buried in the surface is significantly reduced, rendering such nanocomposites less useful as sensors or antibacterial coatings as the nanoparticles work more efficiently if they are directly exposed to the detected media or the bacterial solution. Here, we present a study of a C:H:N:O plasma polymer optimized for efficient attachment of Ag nanoparticles prepared by gas aggregation source onto a film providing enhanced stability in an aqueous environment.
