“…This result is agreement with earlier work using different plant species, such as Aloe vera (Dinesh et al 2015), Phyllanthus niruri (Suresh et al 2015), Moringa oleifera (Sujitha et al 2015), and Caulerpa scalpelliformis (Murugan et al 2015b). FTIR spectra clearly indicate that the biomolecules particularly proteins present in aqueous leaf extract are responsible for synthesis and stabilization of AgNPs (Dhanasekaran and Thangaraj 2013). The functional groups such as alcohol, amines, amides, alkanes, aliphatic, and halides confirmed their presence in AgNPs, and these are the main classes in most of the functional groups.…”

We proposed an effective and eco-friendly control of dengue, malaria, and filariasis-causing vectors. We tested Ipomoea batatas leaves-mediated silver nanoparticles (AgNPs) against first to fourth instar larvae and adults of Aedes albopictus, Anopheles stephensi, and Culex quinquefasciatus at different concentrations. The synthesized AgNPs showed broad spectrum of larvicidal and adulticidal effects after 48 h of exposure. The characterization of synthesized AgNPs was done using various spectral and microscopy analyses. The maximum efficacy was observed in synthesized AgNPs against the adult of Ae. albopictus with the LC and LC values were 10.069 and 15.657 μg/mL, respectively, followed by others.

“…FTIR spectra clearly indicates that the biomolecules especially proteins present in filtrate are responsible for synthesis and stabilization of AgNps (Dhanasekaran and Thangaraj 2013). Sen (2004) reported that the very strong absorption peaks at 1624 and 1600 cm −1 and the strong absorption peaks at 1383 and 1352 cm −1 represents the presence of NO 2 which may be from AgNO 3 solution, the metal precursor involved in the Ag nanoparticle synthesis process.…”

“…Many researchers were reported the microbes like Aspergillus niger, Cladosporium tropicum, Agaricus bisporus, Escherichia coli, Pencillium sp. and Vibrio sp., A. niger 2587, Bacillus thuringiensis, Beauveria bassiana etc., synthesized silver nanoparticles dynamically control the mosquito larvae Prakash 2012, 2013;Dhanasekaran and Thangaraj 2013;. Therefore, in this study, B. megerium was used as reducing and capping agent for synthesis of metal (Ag) nanoparticles for controlling public health promising mosquito vector.…”

Biosynthesis of silver nanoparticles has provoked nowadays and alternative to physical and chemical approaches. In the present study, silver nanoparticles (AgNPs) were synthesized extracellular method using Bacillus megaterium. The AgNPs formations were confirmed initially through color change, and the aliquots were characterized through UV-visible spectrophotometer, followed by scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) spectroscopy, and Fourier transform infrared (FTIR) spectra. The surface plasmon resonance band was shown at 430 nm in UV-vis spectrophotometer. The bioreduction was categorized through identifying the compounds responsible for the AgNP synthesis, and the functional group present in B. megaterium cell-free culture was scrutinized using FTIR. The topography and morphology of the particles were determined using SEM. In addition, this biosynthesized AgNPs were found to show higher insecticidal efficacy against vector mosquitoes. The LC50 and LC90 were found to be 0.567, 2.260; 0.90, 4.44; 1.349, 8.269; and 1.640, 9.152 and 0.240, 0.955; 0.331, 1.593; 0.494, 2.811; and 0.700, 4.435 with respect to the first, second, third, and fourth instar larvae of Culex quinquefasciatus and Aedes aegypti. All the calculated χ (2) values are highly significant compared with the tabulated value. Therefore, B. megaterium-synthesized silver nanoparticles would be used as a potent larvicidal agent against Cx. quinquefasciatus and Ae. aegypti.

“…However, the pattern does not correspond solely to Ag o nanoparticles; probably, there is a mixture of both Ag°and AgCl nanoparticles, as following the JCPDS or ICSD standards. Dhanasekaran and Thangaraj (2013) reported the biogenic synthesis of Ag o nanoparticles from Agaricus bisporus acting on Culex mosquito larvae, however, the XRD pattern revealed the presence of both Ag o nanoparticles and AgCl nanoparticles. Therefore, it is not possible to assign if the effective antimicrobial action of the nanomaterial against larvae was due to Ag°nanoparti-cles or to AgCl nanoparticles, or the combination of both nanoparticles.…”

The antimicrobial impact of biogenic-synthesized silver-based nanoparticles has been the focus of increasing interest. As the antimicrobial activity of nanoparticles is highly dependent on their size and surface, the complete and adequate characterization of the nanoparticle is important. This review discusses the characterization and antimicrobial activity of biogenic synthesized silver nanoparticles and silver chloride nanoparticles. By revising the literature, there is confusion in the characterization of these two silver-based nanoparticles, which consequently affects the conclusion regarding to their antimicrobial activities. This review critically analyzes recent publications on the synthesis of biogenic silver nanoparticles and silver chloride nanoparticles by attempting to correlate the characterization of the nanoparticles with their antimicrobial activity. It was difficult to correlate the size of biogenic nanoparticles with their antimicrobial activity, since different techniques are employed for the characterization. Biogenic synthesized silver-based nanoparticles are not completely characterized, particularly the nature of capped proteins covering the nanomaterials. Moreover, the antimicrobial activity of theses nanoparticles is assayed by using different protocols and strains, which difficult the comparison among the published papers. It is important to select some bacteria as standards, by following international foundations (Pharmaceutical Microbiology Manual) and use the minimal inhibitory concentration by broth microdilution assays from Clinical and Laboratory Standards Institute, which is the most common assay used in antibiotic ones. Therefore, we conclude that to have relevant results on antimicrobial effects of biogenic silver-based nanoparticles, it is necessary to have a complete and adequate characterization of these nanostructures, followed by standard methodology in microbiology protocols.
