“…Therefore, the search for a simple method for the efficient degradation of dyes has gained greater significance. One of such solutions may be the application of metal oxide nanoparticles, which show enhanced catalytic activity in the degradation of organic dyes [38]. The maximum absorbance value of malachite green was recorded at 616 nm.…”

The main objective of this study was synthesis of CuO nanoparticles using extract of Galeopsidis herba and were characterized by UV-Vis spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy (SEM), SEM with EDS profile and transmission electron microscopy (TEM) analysis. SEM images confirmed that synthesized nanoparticles were spherical in nature. EDS profile confirmed the signal characteristic of cooper and oxygen. All the analyses revealed that synthesized CuO nanoparticles were 10 ± 5 nm in size. The antioxidant behavior of synthesized CuO nanoparticles was evaluated by scavenging free radicals of 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH). The DPPH scavenging activity was monitored using UV-Vis spectrophotometer. The synthesized CuO nanoparticles presented very good catalytic activity in the reduction of malachite green.

“…Plant-mediated nanoparticles synthesis is preferred because it is possible to produce large scale nanoparticles with a negligible cost; it is environmental friendly and, at the same time, safe for human therapeutic use [14]. Although synthesis of AgNPs by plant extracts has already been reported with different plants such as Terminalia cuneata [15], Erythrina indica lam [16], Calotropis gigantea L. [17], Pistacia atlantica [18], Cocos nucifera [19], Alternanthera Advances in Natural Sciences: Nanoscience and Nanotechnology Synthesis and characterization of novel silver nanoparticles using Chamaemelum nobile extract for antibacterial application dentate [20], Croton sparsiflorus morong [21], Tribulus terrestris [22], Desmodium gangeticum [23] and Prosopis farcta [24] there is still a lot of attention paid to this field because of the diversity and the high potential of plants in producing nanoparticles with different shapes [18].…”

The present study reports green synthesis of silver nanoparticles (AgNPs) at room temperature using aqueous Chamaemelum nobile extract for the first time. The effect of silver nitrate concentration, quantity of the plant extract and the reaction time on particle size was optimized and studied by UV–Vis spectroscopy and dynamic light scattering. The appearance of brownish color with λmax of 422 nm confirmed the formation of AgNPs. Synthesized nanoparticles were further characterized by Fourier transform infrared spectroscopy, x-ray diffraction and transmission electron microscopy. In addition, antimicrobial activity of the AgNPs against Escherichia coli, Salmonella typhimurium, Staphylococcus aureus and Bacillus subtilis was evaluated based on the inhibition zone using the disc-diffusion assay and measurement of minimal inhibition concentration and minimal bactericidal concentration by standard microdilution method. In conclusion, synthesis of nanoparticle with aqueous Chamaemelum nobile extract is simple, rapid, environmentally benign and inexpensive. Moreover, these synthesized nanoparticles exhibit significant antibacterial activity.

Catalytic reduction of methylene blue and Congo red dyes using green synthesized gold nanoparticles capped by salmalia malabarica gum

Stable gold nanoparticles (AuNPs) were synthesized using salmalia malabarica gum as both reducing and capping agent. It is a simple and eco-friendly green synthesis. The successful formation of AuNPs was confirmed by UV-visible spectroscopy (UV-Vis), Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction and transmission electron microscopy (TEM). The synthesized AuNPs were characterized by a peak at 520-535 nm in the UV-Vis spectrum. The X-ray diffraction studies indicated that the resulting AuNPs were highly crystalline with face-centred cubic geometry. TEM studies showed that the average particle size of the synthesized AuNPs was 12 ± 2 nm. FTIR analysis revealed that -OH groups present in the gum matrix might be responsible for the reduction of Au ?3 into AuNPs. The synthesized AuNPs exhibited good catalytic properties in the reduction of methylene blue and Congo red.
