“…The growing interest in the use of silver nanoparticles (Ag NPs) in various industries (medicine, textile, cosmetics, environment, construction, food packaging, printing, electronics, and home appliance) leads to an increase in their production and usage [1,2]. Due to their antiviral, bactericidal, and fungicidal properties, Ag NPs are used in medicine for diagnosis, treatment, and drug delivery, as well as medical device coating, wound dressings, medical textiles, bone healing, bone cement, dental applications, and coating materials for cardiovascular implants and catheters [3][4][5][6][7].…”

The phytotoxicity of silver nanoparticles (Ag NPs) to plant seeds germination and seedlings development depends on nanoparticles properties and concentration, as well as plant species and stress tolerance degrees. In the present study, the effect of citrate-stabilized spherical Ag NPs (20 mg/L) in sizes of 10, 20, 40, 60, and 100 nm, on wheat grain germination, early seedlings development, and polar metabolite profile in 3-day-old seedlings were analyzed. Ag NPs, regardless of their sizes, did not affect the germination of wheat grains. However, the smaller nanoparticles (10 and 20 nm in size) decreased the growth of seedling roots. Although the concentrations of total polar metabolites in roots, coleoptile, and endosperm of seedlings were not affected by Ag NPs, significant re-arrangements of carbohydrates profiles in seedlings were noted. In roots and coleoptile of 3-day-old seedlings, the concentration of sucrose increased, which was accompanied by a decrease in glucose and fructose. The concentrations of most other polar metabolites (amino acids, organic acids, and phosphate) were not affected by Ag NPs. Thus, an unknown signal is released by small-sized Ag NPs that triggers affection of sugars metabolism and/or distribution.

“…The nanoparticles were stable for at least one month under ambient conditions. Since one of the main properties of AgNPs is their biological activity, so much so that it is currently the main reason for most commercial applications, 45 then the antibacterial and leishmanicidal activities of the synthesized AgNPs were evaluated.…”

This work describes a green synthesis, the characterization, and biological evaluation of silver nanoparticles (AgNPs). The AgNPs suspension was synthesized using aqueous leaf extract of Eucalyptus grandis, which presented a characteristic band at 407 nm in the UV-Vis spectrum. The AgNPs presented a spherical shape and size of 9.7 ± 0.3 nm. The nanoparticles were stable over a month, indicating that E. grandis’ extract is suitable for their preparation and stabilization. The X-ray analysis showed that the crystallinity of AgNPs corresponded to the centered face phase of silver. The antibacterial and leishmanicidal activities of AgNPs were evaluated. The AgNPs presented antibacterial activity on the Gram-negative bacteria Escherichia coli at 53.9 µg mL–1. The leishmanicidal activity evaluation against promastigote forms of Leishmania infantum, Leishmania amazonensis, and Leishmania braziliensis showed that the biological response is dependent on the volume of AgNP suspension. It was demonstrated that L. infantum was more sensitive to the nanoparticle’s treatment than L. amazonensis and L. braziliensis. The treatment of L. infantum promastigotes with 150 µL of AgNP suspension reduced parasite growth by 67.9%, a result which was similar to the treatment with 1 (66.7%) or 2 µL (70.6%) of amphotericin B used as a positive control.

“…Another problem that limits the practical application of these methods is that the product quality is difficult to guarantee, especially the consistency between different batches of plant extracts owing to different growth environments and plant parts. 42 Microbial fermentation will produce some unknown secondary metabolites, which is a hidden danger for biological safety. Additionally, microbial fermentation produces some unknown secondary metabolites, which are hidden dangers to biological safety.…”

The use of natural proteins is a green and effective method for synthesizing silver nanoparticles (AgNPs). Aromatic amino acids of proteins play a reducing role in synthesis, and proteins are coated on the surface of AgNPs to play the role of stabilizers. In this study, we developed an efficient one-step method for synthesizing AgNPs using lysozyme (LYZ) under visible-light irradiation from a xenon lamp in situ. The light conditions and LYZ structure could substantially affect the synthesis. Antibacterial and scald-wound healing results showed that LYZ/AgNPs had broadspectrum and efficient antibacterial activity and promoted scaldwound healing. Therefore, the proposed synthesis method and LYZ/AgNPs have good practical application prospects.
