In particular, the biosafety profiles of plant-derived biosynthetic nanoparticles, developed as environmentally friendly alternatives, are still known to a limited extent. In this study, the cytotoxic and apoptotic effects of iron (Fe), copper (Cu), and silver (Ag) nanoparticles obtained by green synthesis using sage ( Salvia officinalis ) leaf extract on rainbow trout ( Oncorhynchus mykiss ) gonad cell line (RTG-2) were investigated. The structural and morphological properties of the synthesized nanoparticles were characterized by UV–Visible spectroscopy, FT-IR, X-ray diffraction (XRD), scanning electron microscopy (SEM)-EDX, and zeta potential analyses. Cell viability and apoptosis-related protein responses were assessed following nanoparticle exposure. The results showed that all metal nanoparticles produced a concentration-dependent cytotoxic effect in RTG-2 cells. Silver nanoparticles (AgNPs) exhibited the strongest cytotoxic effect, significantly reducing cell viability, especially at concentrations of 50 µg/mL and above. Apoptosis analysis revealed that different toxicity mechanisms were activated depending on the metal type. While AgNPs strongly suppressed BCL2 expression and appeared to enhance apoptosis-related responses, CuNPs and FeNPs were mainly associated with p53-mediated cellular stress signaling. In conclusion, it was shown that sage-derived metal nanoparticles produced metal-type-specific cytotoxic and apoptotic effects in fish gonad cells; these findings highlight the necessity of species- and metal-based approaches in the environmental risk assessment of green synthesis nanoparticles. © 2026 Elsevier B.V.Elsevier B.V.2026Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/10469https://doi.org/10.1016/j.aquatox.2026.1079030166-445XenAquatic Toxicologyinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/10469
