“…The results acquired are identical to previous reported work [33]. The FTIR results are similar to previous reported work on the biochemical constituents in Crocus sativus aqueous extract [39]. The UV spectra showed at 318 nm wavelength, similar results have been in previous published work [28].…”

Plant diseases pose threat to global food security. The excessive use of synthetic agro-chemical engender pesticide resistance. The exploration of alternative sustainable diseases management practices are crucial to overcome the devastative plant diseases. In this study, a facile innocuous approach was adopted for biogenic synthesis of Fe2O3-CsNPs via Crocus sativus corm aqueous extract and was evaluated for their antifungal efficacy against the Verticillium wilt pathogen Verticillium dahliae. The physico-chemical characterization of biosynthesized nanoparticles were performed through UV-visible Spectroscopy, Fourier Transform Infrared Spectroscopy, Energy Dispersive X-ray Spectroscopy, X-Ray Diffraction, and Scanning Electron Microscopy. The fungus mycelium growth was significantly inhibited in the media containing 3mg/mL Fe2O3-CsNPs. Degenerated, concentrated and shriveled hyphae were revealed in Scanning Electron Microscopy. The overall results demonstrated that the biogenic Fe2O3-CsNPs have the efficacy to control devastative phytopathogens.

“…Four strong diffraction peaks were able to be distinctly observed at 2θ of 38.3°, 44.5°, 64.6°and 77.6°, which were respectively associated with (111), (200), (220) and (311) reflection plane of face centered cubic Ag [30], indicating that Ag nanoparticles were successful synthesized using watermelon peel extract based on a green reduction scheme. Noting that, the faint peaks at 2θ of 27.7°, 32.5°and 46.4°were also shown in this XRD curve, corresponding to AgCl nanoparticles as described in [31]. The reason was that, during Ag nanoparticles green synthesis process, a very small amount of AgCl compounds may be yielded because Ag + can be bonded to a trace amount of Cl − from watermelon peel extract.…”

Ag nanoparticles displayed a more attractive application in solar-driven interfacial evaporation for seawater desalination, but their synthesis process was expensive and detrimental to the environment due to the consumption of chemicals. In this work, we green-synthesized Ag nanoparticles using watermelon peel extract as reducing agent, while the membrane with Ag nanoparticles was prepared for solar-driven interfacial evaporation. Moreover, the evaporation performance of the membranes with different Ag nanoparticles loadings was investigated, as well as the reusability and desalination application was also explored. The experimental results showed that the membrane with Ag nanoparticles loading of 0.05 g exhibited superior evaporation performance, corresponding to the evaporation rate of 1.37 kg m −2 h −1 and the evaporation efficiency of 89.3%, respectively. In addition, the membrane with Ag nanoparticles possessed an excellent recyclability and concentration of ions in the desalinated seawater reached the potable water standard. Our research demonstrated that Ag nanoparticles green-synthesized by watermelon peel extract was an ideal candidate applied in solardriven interfacial evaporation for seawater desalination.

“…The destruction of the bacterial cell wall may also be attributed to the release of ROS (reactive oxygen species) that can damage membrane protein and nucleic acid [52,53]. Bagherzadeh et al [54] compared the antibacterial effects of biosynthesized AgNPs prepared using saffron extract and market purchased AgNPs and showed that the extract of the saffron plant and purchased AgNPs did not show enough antibacterial effects but biosynthesized AgNPs exhibited promising antibacterial activity. Anandalakshmi et al synthesize AgNPs using aqueous leaves extract of plant Pedalium murex, characterized them and investigate their antibacterial activity and concluded that green synthesis is eco-friendly and produce AgNPs that have a potential antibacterial effect against S. aureus, P. aeruginosa, E. coli, Mariniluteicoccus flavus, Bacillus subtilis, and Bacillus pumilus [55].…”

Surface engineered nanoparticles (NPs) are of great attention due to their targeted medical applications. The nature of the functionalized surface plays a vital role in achieving the required functionalities of engineered NPs. Owing to the biofilm formation capabilities of wound associated pathogens, impaired wound healing is a major complication in the medical field. In this context, herein, we report the biogenic synthesis of Flacourtia indica (FI) based NPs, i.e., FI-AgNPs using the aqueous leaf extract of this anti-bacterial herb. The newly developed FI-AgNPs were characterized using various analytical and imaging techniques such as UV-Vis spectroscopy, Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The FI-AgNPs showed potent anti-microbial activity and anti-biofilm potential which were examined through a test tube adherence method and congo red agar method. It has been observed that synthesized FI-AgNPs inhibit the formation of a biofilm of observed bacteria, even at a minimum concentration of 80 μgml −1 . These findings suggest that synthesized FI-AgNPs could be used against wound associated microbes, especially bacterial coating on medical devices, to prevent antibiotic-resistant biofilm infections. Further development and research are obligatory to decode this skill into preventive and therapeutic strategies.
