Green synthesis of finely-dispersed highly bactericidal silver nanoparticles via modified Tollens technique

Decoration of Silver Nanoparticles on Multiwalled Carbon Nanotubes: Antibacterial Mechanism and Ultrastructural Analysis

“…Our previous reports [17,18] showed that the Tollens process enables us to produce silver colloids with small sizes and stable aqueous dispersions at high yield ∼99%. In our present work, we employed this process to decorate silver NPs on the surface of MWCNTs with yield ∼98%.…”

“…The silver nanoparticles were prepared by using a modified Tollens process as reported elsewhere [17,18]. Briefly, 1.7 g (10 mmol) of AgNO 3 was dissolved in 100 mL of deionized water.…”

Silver Nanoparticles: Green Route, Stability and Effect of Additives

“…Considerable spectroscopic data have accumulated on the synthesis of various Ag-NP by silver-mirror reaction. It has been established that ammonia concentrations and nature of reducing agents play an important role in controlling the morphologies of NP [27,28]. However, details of silver(I) reduction (Ag-NP formation) involving oxalic acid as reductant are not yet well-known in the absence and presence of additives or ammonia.…”

“…We have chosen oxalic acid to see the effects of different additives, because its oxidation product, i.e., CO 2 , has no complex-formining tendency. A study of such a redox reaction should provide information relevant to the hypothesis previously advanced to the silver-mirror reaction [29,30]. We have carried out the present study with the following aims: (1) to determine the effects of different variables on the rates of Ag-NP; (2) to establish the role of different additives and ammonia on the growth of Ag-NP; and (3) to determine the effects of inorganic salts on the stability of silver sol.…”

Do Chenopodium ambrosioides-Synthesized Silver Nanoparticles Impact Oryzias melastigma Predation Against Aedes albopictus Larvae?

“…Recently, silver nanoparticles (AgNP) gained a focus of intensive research owing to their wide range of applications in areas such as catalysis, optics, antimicrobials, pesticides, biomedical and biomaterial production [7,39,64,126]. The biological synthesis of metal nanoparticles is a research area currently considered more ecofriendly and cost-effective, if compared to other chemical and physical methods [3,11].…”
