“…Nanotechnology is advantageous in the biomedical, health care, domestic appliances, food sector, and wastewater treatment due to its wide range of applications history (Thipe et al, 2022) that nanotechnology mostly works based on nanoparticles (NPs), with silver nanoparticles (AgNPs) being one of the most important and fascinating nanomaterials (Zaheer Ud Din et al, 2023) and are frequently used in medicine due to their vast biological activity (Hossain et al, 2022; Kakakhel, Wu, Sajjad, et al, 2021). NPs are a particular form of a nanosized material having distinguishing characteristics due to their tiny size and dispersion (Ismail et al, 2022). AgNPs have a variety of biological functions and significant applications, however, their toxicity to humans and the environment is not fully understood (Sobi et al, 2022).…”

Silver nanoparticles (AgNPs) are widely used and have various applications, including medicine, electronics, and textiles. However, their increasing use raises concern about their potential environmental impact, particularly on aquatic organisms, such as fish, which are the primary consumers of aquatic environments and can be exposed to AgNPs through various routes. For this purpose, the leaves of the plant species Bellis perennis were used as a reductive agent to convert silver nitrate into AgNPs, to assess its toxicity against fish. Well‐dispersed and undersized AgNPs were obtained and confirmed using analytical techniques, including Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). Moreover, the AgNPs have shown significant antibacterial activity against Aeromonas hydrophila (25.71 ± 0.63) and Vibrio harveyi (22.39 ± 0.29). In addition, the toxicity of the obtained AgNPs was assessed by exposing Cyprinus carpio to various concentrations, including 0.06, 0.1, and 0.2 mg/L. The findings revealed that the AgNPs were significantly accumulated in the intestine, followed by the gills, liver, muscles, kidney, and brain. This bioaccumulation led to histological alterations and destruction in the villi of the intestine, regeneration of liver cells, and degeneration of the gill lamella.Research Highlights Plants based synthesis of AgNPs is mostly considered as eco‐friendly A significant antibacterial activity was obtained The plant mediated AgNPs were found less toxic The AgNPs was profoundly accumulated and causes histological alterations
