“…One of the advantages for using starch as a stabilizing agent, aside from its potential power to convert the ions of silver to zero-valent silver, is the presence of huge hydroxy groups that stabilize the formed nanoparticles in nanoform. In our published work 7 , 28 , 43 – 47 , the prepared nanoparticles were extensively characterized using advanced tools. Secondly, as mentioned in the experiment part for the preparation of SiO 2 NPs, condensation reaction was performed for this synthesis.…”

Silver nanoparticles (AgNPs) have been used as a promising alternative to antibiotics in poultry feed. In this study, silver-doped silica nanoparticles (SiO2@AgNPs) were prepared in powder form, using starch, via the chemical reduction method and sol–gel technique followed by full characterization. SiO2@AgNPs were added to the poultry diet at three doses (2, 4, and 8 mg/kg diet). The safety of the oral dietary supplementation was estimated through the evaluation of the growth performance and hematological, biochemical, and oxidative parameters of birds. Moreover, the immunohistochemical examination of all body organs was also performed. Results of this study showed that SiO2@AgNPs have no negative effects on the growth performance and hematological, biochemical, and oxidative parameters of birds. Moreover, the immunohistochemical examination revealed the minimum inflammatory reactions and lymphoid depletion under a dose level of 8 mg/kg. In conclusion, SiO2@AgNPs could be considered as a promising and safe nano-growth promoter in broilers when added to poultry diet under a dose level of 4 mg/kg diet.

“…represent the greatest vital economically damaging genera of phytoparasitic nematodes on horticultural and field crops by more than 3000 host species 2 . The four common root-knot nematode species, namely Meloidogyne incognita, M. javanica, M. Arenaria, and M. hapla are the most abundant and damaging nematodes of vegetables 3 , 4 . The root-knot nematode M. javanica causes serious damage in vegetable crops 5 .…”

Tomato (Solanum Lycopersicum L.) is an important vegetable crop that belongs to the family Solanaceae. Root-knot nematodes reflect the highly critical economically damaging genera of phytoparasitic nematodes on tomato plants. In this study, the eco-nematicide activity of freshwater green macroalga Cladophora glomerata aqueous extract and their synthesized silver nanoparticles (Ag-NPs) against root-knot nematodes Meloidogyne javanica was investigated on tomato plants. The formation and chemical structure of Ag-NPs was examined. The aqueous extract from C. glomerata was applied against the root-knot nematodes besides the biosynthesized green silver nanoparticles with 100, 75, 50, and 25% (S, S/2, S/3, S/4) concentrations. To investigate the plant response toward the Green Synthesized Silver Nanoparticles (GSNPs) treatment, expression profiling of Phenylalanine Ammonia-Lyase (PAL), Poly Phenol Oxidase (PPO), and Peroxidase (POX) in tomato were examined using Quantitative Real-Time PCR (Q-PCR). The results indicated that GSNPs from C. glomerata exhibited the highest eco-nematicide activity in the laboratory bioassay on egg hatchability and juveniles (J2S) mortality of M. javanica compared with the chemical commercial nematicide Rugby 60%. Also, results showed a significant reduction in galls number, egg masses, females per root system/plant, and mortality of juveniles. The results of PAL and PPO enzyme expression for the control plants remained relatively stable, while the plant inoculated with nematode M. javanica as well as the activity of genes in scope was increased from 14 to 28 Days after Nematode Inoculation (DANI). These activities were improved in inoculated plants and treated with C. glomerata extract and their green syntheses of Ag-NPs and the other plants treated with Rugby 60% (4 mL/L). The greatest activities of the three enzymes were evident after 14 days after the nematode inoculation. It can be concluded that the green synthesized nanoparticles using C. glomerata could be used as potent nematicides against M. javanica which induces the immune system to defend against nematode infection.

“…In this work, histopathological examination of the liver, kidney, thymus, bursa, and spleen from control and SiO 2 @AgNP-treated chickens (8,16, and 20 mg) revealed moderate to severe pathological lesions with severity that correlated with the level of SiO 2 @AgNP supplementation. The reported lesions were in the form of diffuse mononuclear in ammatory in ltrates, necrotic and degenerative changes in hepatic and renal tissues, and even broplasia in hepatic portal triads, in addition to lymphoid cell depletion in spleen, thymus, and bursa.…”

“…Silver nanoparticles (AgNPs) have physical and chemical properties that are distinct from those of their larger counterparts due to their chemical stability and very large surface-to-volume ratio [5][6][7][8] . Nanosilver solution is composed of colloidal suspensions of silver ions, which is more stable than other solutions.…”

Silver nanoparticles (AgNPs) are a powerful disinfectant, but little information is available on their potential use as a growth promoter and the safety margin of this. In this study, 480 1-day-old Cobb chicks were assigned to one control and three treated groups. The treated groups were supplemented with silver-doped silica nanoparticles (SiO2@AgNPs) at three dietary levels (8, 16, and 20 mg/kg diet) for 35 days. The results revealed no significant changes in the growth performance and oxidative parameters, and in most of the hematological and biochemical parameters among the control and treated groups. In contrast, dose-dependent adverse effects were exerted on the histopathological structure and immunohistochemical expression of CD45 in liver, kidneys, and lymphoid organs (spleen, bursa, and thymus). In addition, the relative weight of lymphoid organs and the serum levels of immunoglobulins M and G were significantly diminished. Moreover, the gene expression of proinflammatory cytokines (IL-β1 and TNF-α) and the ultrastructural morphology in breast muscle showed significant dose-dependent alterations. It could be concluded that the dietary supplementation of SiO2@AgNPs at a level of 8 mg/kg diet or more has dose-dependent proinflammatory and immunosuppressive effects on broiler chickens.
