“…Probably for this reason, green silver nanoparticles (G-AgNPs) have high biological activity compared to common synthetic nanoparticles (C-AgNPs1 and C-AgNPs2). According to previously published articles, green synthesis nanoparticles (especially green silver nanoparticles) are less toxic than nanoparticles synthesized by non-green methods due to the absence of harmful and environmentally dangerous substances to wildlife and humans 77 , 78 . Therefore after supplementary studies about exact dose and toxicity of G-AgNPs they were applicable in the various industries.…”

In the present work, Silver nanoparticles (AgNPs) were fabricated through the dandelion flower hydroalcoholic extract, and their properties were characterized by FTIR, XRD, UV visible, SEM, and EDX. The results demonstrated that the average diameter of the green fabricated AgNPs is 45–55 nm (G-AgNPs). The antioxidant, antimicrobial, antidiabetic, and photocatalytic properties of G-AgNPs were compared with two commercially available different diameter sizes (20 and 80–100 nm) of AgNPs (C-AgNPs1- and C-AgNPs2, respectively). The sample's capacity for antioxidants was evaluated by DPPH free radical scavenging method. The consequences showed that G-AgNPs have higher radical scavenging activity (47.8%) than C-AgNPs2 (39.49%) and C-AgNPs1 (33.91%). To investigate the photocatalytic property, methylene blue dye was used. The results displayed that G-AgNPs is an effective photo-catalyst compared to C-AgNPs2 and C-AgNPs1, which respectively have an inhibition potential of 75.22, 51.94, and 56.65%. Also, the antimicrobial capacity of nanoparticles was assayed against, the gram-negative Escherichia coli and gram-positive Staphylococcus aureus bacteria. The results indicated that G-AgNPs could effectively inhibit the growth of both bacteria, compared to C-AgNPs1 and C-AgNPs2. Finally, G-AgNPs exhibited a considerable α-glucosidase enzyme inhibitory effect (88.37%) in comparison with C-AgNPs1 (61.7%) and C-AgNPs2 (50.5%).

“…Green MNPs have demonstrated lesser toxicities and adverse effects than chemically induced MNPs. Green silver nanoparticles (AgNPs) elucidated a lower rise in a number of hematological indicators of treated fish when compared with chemically prepared AgNPs [ 18 ]. At relatively modest doses (6.25–25 μl), the Ferula asafetida AgNPs were fatal to lung and cervical carcinoma cell lines and down-regulated the expression of PIK3CA and KRAS oncogenes, indicating their efficacy, safety and tolerability [ 19 ].…”

In green biological synthesis, metal nanoparticles are produced by plants or microorganisms. Since it is ecologically friendly, economically viable and sustainable, this method is preferable to other traditional ones. For their continuous groundbreaking advancements and myriad physiochemical and biological benefits, nanotechnologies have influenced various aspects of scientific fields. Metal nanoparticles (MNPs) are the field anchor for their outstanding optical, electrical and chemical capabilities that outperform their regular-sized counterparts. This review discusses the most current biosynthesized metal nanoparticles synthesized by various organisms and their biological applications along with the key elements involved in MNP green synthesis. The review is displayed in a manner that will impart assertiveness, help the researchers to open questions, and highlight many points for conducting future research.

“…A study reported that AgNPs are toxic and hazardous to ecosystems due to their small size (Ranjani et al, 2019), and based on silver ions in 0, + 1 , + 2 , + 3 , and + 4 oxidation states (Hassan et al, 2023). However, due to a lack of knowledge, precise predictions of AgNPs toxicity are still restricted (Younas 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
