“…Silver has been known as a broad-spectrum bactericide for centuries. It has been demonstrated that silver nanoparticle coatings on Ti based implants increased their biocompatibility and antibacterial properties (Gyorgyey et al 2016;Sulej-Chojnacka et al 2016). Titanium dioxide (TiO 2 ) has also been known as a broad-spectrum bactericide for a long time.…”

It has been demonstrated that Ag-TiO 2 nanocomposite coatings with excellent antimicrobial activity and biocompatibility have the potential to reduce infection problems. However, the mechanism of the synergistic effect of Ag-TiO 2 coatings on antibacterial efficiency is still not well understood. In this study, five types of Ag-TiO 2 nanocomposited coatings with different TiO 2 contents were prepared on a titanium substratum. Leaching tests indicated that the incorporation of TiO 2 nanoparticles into an Ag matrix significantly promoted Ag ion release. Surface energy measurements showed that the addition of TiO 2 nanoparticles also significantly increased the electron donor surface energy of the coatings. Bacterial adhesion assays with Escherichia coli and Staphylococcus aureus demonstrated that the number of adhered bacteria decreased with increasing electron donor surface energy. The increased Ag ion release rate and the increased electron donor surface energy contributed to an enhanced antibacterial efficiency of the coatings.

“…Preventing or limiting post-implantation infections has been also evidenced in the case of titanium-based devices modified with hydrothermally transformed [132] or plasmasprayed [133] hydroxyapatite coatings enriched with nanosilver: additional enhanced bone stability and osteoinductive ability has been reported. Embedding nanosilver within polydopamine-based coatings [134] and hierarchical layers [135] proved an effective strategy to boost the infection-free osseointegration of thermoplastic implantable devices, as evidenced against E. coli and S. aureus strains, with additional osteogenic and angiogenic effects.…”

Exploring silver-based and carbon-based nanomaterials’ excellent intrinsic antipathogenic effects represents an attractive alternative for fabricating anti-infective formulations. Using chemical synthesis protocols, stearate-conjugated silver (Ag@C18) nanoparticles and graphene oxide nanosheets (nGOs) were herein obtained and investigated in terms of composition and microstructure. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) characterizations revealed the formation of nanomaterials with desirable physical properties, while X-ray diffraction (XRD) analyses confirmed the high purity of synthesized nanomaterials. Further, laser-processed Ag@C18-nGO coatings were developed, optimized, and evaluated in terms of biological and microbiological outcomes. The highly biocompatible Ag@C18-nGO nanostructured coatings proved suitable candidates for the local modulation of biofilm-associated periprosthetic infections.
