“…The antibacterial activity of AgNPs synthesized with Rosmarinus officinalis extracts was tested against gram-positive bacteria, and the maximum zones of inhibition at dosages of 20, 40, and 80 mg/disk were 21.52, 30, and 31.2 mm, respectively, against S. aureus and 13.4, 15.63, and 16.21 mm, respectively, against Bacillus subtilis [ 85 ]. The antimicrobial activity of the medicinal plant Onosma dichroantha and antimicrobial activity of silver chloride nanoparticles suggest a novel approach to the development of bactericides applicable to a wide range of applications, such as the treatment of burn wounds and injuries [ 86 ].…”

Interest in “green nanotechnology” in nanoparticle biosynthesis is growing among researchers. Nanotechnologies, due to their physicochemical and biological properties, have applications in diverse fields, including drug delivery, sensors, optoelectronics, and magnetic devices. This review focuses on the green synthesis of silver nanoparticles (AgNPs) using plant sources. Green synthesis of nanoparticles is an eco-friendly approach, which should be further explored for the potential of different plants to synthesize nanoparticles. The sizes of AgNPs are in the range of 1 to 100 nm. Characterization of synthesized nanoparticles is accomplished through UV spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, and scanning electron microscopy. AgNPs have great potential to act as antimicrobial agents. The green synthesis of AgNPs can be efficiently applied for future engineering and medical concerns. Different types of cancers can be treated and/or controlled by phytonanotechnology. The present review provides a comprehensive survey of plant-mediated synthesis of AgNPs with specific focus on their applications, e.g., antimicrobial, antioxidant, and anticancer activities.

“…[11] The components present in the walnut green husk extract might be considered as the source of chloride in the reaction solution for the formation of AgCl-NPs. [3,12] FTIR spectroscopy was performed to identify the extract components attached to the synthesised nanoparticles and the data are shown in Figure 2. The regions indicated by arrows at 3409, 2930, 1604 and 633 cm ¡1 correspond to ÀOH, ÀCH, CHC and aromatic stretches, respectively, demonstrating the presence of considerable amounts of these residues in the samples which might be related to phenol and polyphenolic components present in the extract that can potentially act as capping and stabilising biomolecules in green synthesis of AgCl-NPs.…”

Nanoparticles have gained significant attention in recent years due to their numerous applications in various aspects of human life. A variety of methods have been investigated for synthesis of nanoparticles among which, biogenic approaches are considered as both simple and ecofriendly. Here, a new single-step biological approach was employed for synthesis of silver chloride nanoparticles (AgCl-NPs) at room temperature, using walnut green husk extract. Macromolecules present in the plant extract, which might act as bio-reductants and/or stabilisers of nanoparticles were characterised by Fourier transform Infrared spectroscopy. X-ray diffraction pattern and transmission electron microscopy revealed that 1 mM of AgNO3 produced mostly spherical nanoparticles in a range of 4À30 nm in diameter with an average of 16 nm. Interestingly, the synthesised nanoparticles showed significant inhibitory effects against Escherichia coli and Staphylococcus aureus clinical isolates. Altogether, these data suggest a new encouraging application of a medicinal plant bound with synthesised AgCl nanoparticles.

“…In particular, the latter have been widely reported for the synthesis of AgNPs using plants extracts [1]. In contrast, the synthesis of AgClNPs has been reported less frequently [2]. Considering the diversity of plants and their ability to synthesize nanoparticles, there are certainly opportunities to obtain technologically interesting materials.…”
