“…The green synthesized AgNPs were successfully used for the degradation of hazardous dyes such as methylene blue, methyl orange, direct yellow 12, reactive black 5, rhodamine B, Congo red and so on. All the tested dyes underwent rapid degradation in the presence of a silver nanocatalyst, following pseudo-first order reaction kinetics [26,44,45]. Silver nanoparticles mediated catalytic reductive degradation of azo dyes has been largely investigated due to its efficacy.…”

The present article reports an environmentally benign method for synthesizing silver nanoparticles using the fruit extract of Viburnum opulus L. as a source of bioactive compounds, which can act as reducing agents of the silver ions and also as stabilizing agents of the obtained nanoparticles. The catalytic ability of the synthesized silver nanoparticles (AgNPs) to remove toxic organic dyes was also evaluated. The biosynthesis of silver nanoparticles was firstly confirmed by UV-Vis spectral analysis, which revealed the presence of the characteristic absorption peak at 415 nm corresponding to the surface plasmon vibration of colloidal silver. Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) studies were conducted to confirm the presence of bioactive phytocompounds, especially phenolics, as capping and stabilizing agents of the AgNPs. The size, morphology and crystalline nature of the synthesized AgNPs were investigated by transmission electron microscopy and X-ray diffraction techniques revealing that the obtained nanoparticles were spherical shaped, with an average diameter of 16 nm, monodispersed, face centered cubic nanoparticles. Further, the catalytic ability in the degradation of tartrazine, carmoisine and brilliant blue FCF dyes by NaBH4 was evaluated. The results demonstrated an efficient activity against all the investigated dyes being an outstanding catalyst for the degradation of brilliant blue FCF. This eco-friendly synthetic approach can generate new tools useful in environmental pollution control.

“…The solution was then subjected to 10,000 rpm for 15 minand the pellet was washed and stored for further usage. The AgNPs were characterized by the KBr method and the spectral scanning was carried out using the FT-IR spectroscopy using Nicolet FT-IT (AVATAR-330) with a narrow band of mercury/cadmium/telluride [12,13]. The synthesized AgNPs were further subjected to phase identification using X-ray diffraction.…”

Quickly developing industrialization is one of the significant benefactors of natural contamination as it presents awful difficulties for the earth and the ordinary citizens. Biological synthesis of the silver nanoparticles (AgNPs) atthe presence of the aqueous leaf extract of Celosia argentea, funtioned as the reducing and capping agent. In this research study, we are reportthe synthesis of the AgNPs with the optimized experimental parameters at the pH. Formation of the AgNPs was confirmed by the UV-Visible spectroscopy and FT-IR analysis. The structural characterization was carried using the SEM-EDX, providing the size of the nanoparticles to be 50-80 nm. The AFM showed the spherical surface topology, the zeta potential whereas, particle size analysis showed stability and the average size was determined to be 50 nm.

“…Some of the unique properties of these nanoparticles are good conductivity, chemical stability, and catalytic efficiency and most importantly their antifungal, anti-viral, anti-inflammatory, anti-angiogenic, and anti-cancer activities with less toxicity and enhanced bioavailability [4][5][6][7]. In addition to the above-mentioned applications, AgNps are also being successfully used for the diagnosis and treatment of cancer [8,9].…”

AbstractThis study was focused to synthesize silver nanoparticles (AgNps) from the aqueous extract of Bistorta amplexicaule and to evaluate their antimicrobial, antifungal, and 4-nitrophenol (4-NP) degradation potential. The AgNps from B. amplexicaule were characterized by field emission scanning electron microscopy, energy dispersive X-ray spectrometry, X-ray diffraction, and X-ray photoelectron spectroscopy studies. The biological activity of the AgNps was checked against the three bacterial and two fungal strains. The inhibition activities of the synthesized nanoparticles on pathogenic bacteria and fungi were equally studied using the colony-forming unit method. The AgNps synthesized showed excellent bactericidal and fungicidal activities against pathogenic Escherichia coli, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus (MRSA), Candida albicans, and Candida tropicalis. The removal of nitrophenols is one of the most demanding tasks, due to their injurious impact on the health of the living organisms. The AgNps showed superior performance compared with the pure plant extract. The AgNps also displayed efficient catalytic ability in reducing toxic 4-NP into harmless 4-aminophenol in the presence of NaBH4 solution. Hence, the synthesized AgNps can be effectively used against bacterial and fungal infections and in the decontamination of 4-NP polluted water.
