“…Correspondingly, Lin et al investigated the antimicrobial activity of Ag NPs deposited on the substrate, reporting inhibition against the tested pathogens. 31 In our current investigation, a similar enhancement in inhibition was noted across all strains compared to previous studies, possibly attributable to the presence of a complex and low-permeability cell wall structure in the pathogens under scrutiny. The results of this experiment demonstrate improved in vitro antimicrobial activity and cytocompatibility of the synthesized composites.…”

Polyetheretherketone (PEEK), particularly its sulfonated form (SPEEK), has emerged as a promising synthetic biomaterial for artificial bone implants, providing an alternative to conventional titanium metal. However, postoperative infections pose a critical challenge, driven by diverse and antibiotic-resistant bacteria. To address this issue, we propose the modification of the SPEEK surface using a thin graphene oxide (GO) film containing silver (Ag) ions. The resulting coating exhibits substantial antibacterial effects against various pathogens, including Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Candida albicans. Experimental assessments elucidate the coating’s impact on bacterial adhesion, biofilm formation, and morphology. The results suggest that hindered bacterial growth stems from reduced biofilm production and the controlled release of Ag ions facilitated by the GO coating. The Ag/GO-SPEEK material holds promise as a bioactive implant, addressing the challenges associated with bacterial targeting in bone tissue engineering applications.
