“…Also, Shahabuddin and his team in 2020 (Shahabuddin et al, 2020) reported green synthesized small size (5–16 nm) spherical Ag NPs from Catharanthus roseus dried barks extract doped with graphene oxide to be an excellent degradation agent with almost a complete removal of MB in less than 5 min and the smaller‐sized Ag NPs exhibited higher photocatalytic activity than the larger nanoparticles because the surface of the nanoparticles with smaller size easily adhered to the reactants thus increases the rate of degradation (Nandhini et al, 2019; Shahabuddin et al, 2020). This is similar to the result obtained by (Barman et al, 2019; Naseem et al, 2020) using Citrus paradisi peel and Zingiber officinale rhizome extract as a reducing agent to fabricate a spherical 14.84‐nm and triangular 43.28‐nm Ag NPs respectively.…”

The advent of global industrialization advancements has proven to be both a blessing and a curse for humanity, with significant detrimental consequences on marine bodies, and methylene blue is one of the common offenders through textile industry runoffs. These dye runoffs are complex, neurotoxic, and carcinogenic and prevent sunlight from penetrating the water to hinder photosynthesis and increase the biological/biochemical oxygen demand (BOD), hence hampering the ontogenesis of photoautotrophic organisms and thus threatening marine life and causing an increase in unavailability and inaccessibility to healthy water for eco‐fundamental networking. Traditional methods came into the limelight, but they are costly and inefficient. Amazingly, due to exceptional surface features, eco‐friendliness, cost‐effectiveness, catalytic efficiency, and antibacterial capabilities, biosynthesized nanoparticles emerged as a potential solution to these drawbacks encounter by the traditional approach. This review was based on a comprehensive review of publicly available literature (majorly 2019–2021 original research reports) using major scientific databases such as SciFinder, Scopus, PubMed, Google Scholar, and Science Direct. The keywords that were utilized to scoop up the scientific journals were as follows: dye degradation and decolorization, biosynthesis, methylene blue, silver nanoparticles, wastewater, and dye runoffs. Thus, this review highlights the green sources used for the bio‐fabrication of silver nanoparticles, the current level of knowledge of biosynthesis mechanism, mechanism of degradation, and methylene blue dye degradation efficiency. Practitioner Points Bio‐fabrication mechanism of green silver nano‐architecture from plant, bacteria, fungi, and algae extract has been discussed. Various biological capping/reducing agents have been reported. Degradation efficiency of methylene blue dyes using silver nanoparticles has been discussed. Mechanism of degradation of methylene blue by green silver nanoparticles has been reported.

“…The shift can be relative to a new compound(s), that is, leucomethylene blue resulted from degradation of day. [ 46 ] The relative absorbance of MB following treatment with Drac‐AgNPs calculated 67% degradation after 48 h (Figure 9). Darc‐AgNPs showed intense catalytic activity comparing to our previous works, where degradation of MB calculated 57% and 44% using biogenic AgNPs and AuNPs synthesized by N. arvensis infusion [ 44,47 ] and 62% for biosynthesized AuNPs using leaf infusion of D. kotschyi .…”

The discovery and development of active compounds to eliminate drug resistance and side effects is a crucial process. In this study, the leaf infusion of Dracocephalum kotschyi Boiss as a novel green alternative is used to synthesize silver nanoparticles (Drac‐AgNPs). Antibacterial, cytotoxicity effects, hemocompatibility, and the catalytic properties of these nanoparticles are evaluated. The synthesis of Drac‐AgNPs is confirmed by UV–vis spectroscopy, X‐ray diffraction, Fourier‐transform infrared spectroscopy, and transmission electron microscopy, where Drac‐AgNPs are spherical, with a size range of 5–63 nm. Their IC50 values against H1299 and MCF‐7 cell lines are above 50 and 100 μg mL−1, respectively. Drac‐AgNPs are effective against an inclusive range of the gram‐positive and gram‐negative bacteria, that is, Staphylococcus epidermidis, Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Serratia marcescens, and Pseudomonas aeruginosa, and a low hemolytic effect makes them an exceptional AgNP with a great hemocompatibility. They show a moderate catalytic‐effect in terms of removing methylene blue, with 67% degradation. Altogether, Drac‐AgNP, as a multi‐tasker material, shows potential for the prevention and treatment of infections and photothermal/chemotherapy of cancers.

“…The absorption spectra show the characteristics peaks located at 400-480 nm of bare Ag and CTAB@Ag nanoparticles. The broad peaks suggested the formation of various shape and size of Ag nanoparticles [35]. The optical band of bare Ag and CTAB@Ag nanoparticles were calculated using Tauc's plot [36].…”

“…Strong and medium intensity bands are observed in bare Ag and CTAB@Ag at 1444-1473 cm −1 , 1348-1361 cm −1 , 1152-1183 cm −1 attributed due to presence of methyl group, ether, alcohol. Some others bands at 996-1017 cm −1 , 754-760 cm −1 and 567-608 cm −1 are signi cant indicators of heterocyclic chemicals such as avonoids and alkaloids, which are active components of Z. o cinale and serve as a capping agent [35,37,38].…”

In the present study, ginger extract, which is widely available as a medicinal herb, is used to develop a facile method for green synthesis of bare Ag and surfactant capped CTAB@Ag nanoparticles via Hydrothermal route. The as-prepared Ag nanoparticles were characterized by UV-Vis spectroscopy, photoluminescence (PL), X-ray Diffraction (XRD), Infrared spectroscopy (IR), and Scanning electron microscopy (SEM). The catalytic properties of as prepared bare and surfactant capped CTAB@Ag nanoparticles were also investigated in reductive degradation of Methyl Orange (MO) dye and 4-Nitrophenol (4-NP). Surfactant-capped CTAB@Ag nanoparticles exhibit superior catalytic properties in the degradation of MO and conversion of 4-nitro phenol to 4-amino phenol when compared to bare silver nanoparticles.
