“…Soni and Prakash (2011) demonstrated the presence of Ag o nanoparticles together with silver oxides mixtures and other impurities from F. oxysporum Schltdl 2480 and from Chrysosporium tropicum Carmichael-2828 strains. Penicillium atramentosum KM was suggested to be able to produce Ag o nanoparticles; however, the XRD pattern represented a mixture of silver oxide nanoparticles and not Ag o nanoparticles (Sarsar et al 2015). Aspergillus foetidus (Roy and Das 2015) demonstrated mainly the presence of Ag o nanoparticles; however, traces of AgCl nanoparticles were also observed in the XRD pattern and not discussed in the publication.…”

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.

“…For instance, metabolites of some arthropods have been used for green synthesis of nanoparticles [2][3][4][5]. In several studies, metabolites and enzymes of microbial origin (fungi and bacteria), even whole microbes have been used in the synthesis of nanoparticles [6][7][8][9][10][11], while many others have reported the synthesis of nanoparticles by employing extracts from various parts of the plants such as seeds, fruits, flowers, leaves, stem and roots [12][13][14][15][16][17][18][19]. Kaviya et al [20], Njagi et al [21] and Roopan et al [22] synthesized AgNPs using Sorghum spp bran extract, Citrus cinensis peel extract and Cocos nucifera coir, respectively, suggesting the usefulness of agro-wastes in green nanotechnology.…”

The present investigation reports utility of cocoa pod husk extract (CPHE), an agro-waste in the biosynthesis of silver nanoparticles (AgNPs) under ambient condition. The synthesized CPHE-AgNPs were characterized by UVvisible spectroscopy, Fourier-transform infrared spectroscopy, Energy dispersive X-ray (EDX) spectroscopy and transmission electron microscopy. The feasibility of the CPHE-AgNPs as antimicrobial agent against some multidrug-resistant clinical isolates, paint additive, and their antioxidant and larvicidal activities were evaluated. CPHE-AgNPs were predominantly spherical (size range of 4-32 nm) with face-centered cubic phase and crystalline conformation pattern revealed by selected area electron diffraction, while EDX analysis showed the presence of silver as a prominent metal. The synthesized nanoparticles effectively inhibited multidrug-resistant isolates of Klebsiella pneumonia and Escherichia coli at a concentration of 40 lg/ml, and enhanced the activities of cefuroxime and ampicillin in synergistic manner at 42.9-100 % concentration, while it completely inhibited the growth of E. coli, K. pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, Pseudomonas aeruginosa, Aspergillus flavus, Aspergillus fumigatus and Aspergillus niger as additive in emulsion paint. The antioxidant activities of the CPHE-AgNPs were found to be excellent, while highly potent larvicidal activities against the larvae of Anopheles mosquito at 10-100 lg/ml concentration were observed. Our study demonstrated for the first time the utility of CPHE in the biosynthesis of CPHE-AgNPs with potential applications as antimicrobial and larvicidal agents, and paint additives for coating material surfaces to protect them against microbial growth while improving their shelf life.

“…Synthesis of nanoparticles via biosynthetic process provided nontoxic, eco-friendly and economic through an alternative to the various chemical and physical methods. Microbial such as yeasts, mold fungi, and bacteria are mostly preferred for nanoparticles biosynthetic due to their rapid rate of growth, ease of cultivation and their ability to grow at obtainable conditions of pressure, pH and temperature [5]. In a previous study, pointed out that bacterial sp.…”

“…Many researches confirmed that the biosynthetic of silver nanoparticles using via chemical process produce some unwanted materials which absorbed on the surface of the nanoparticles may have hostile effects in medical applications. Thus, many of the latest antibacterial agents developed in the last decades; none of them has been achieved its activity against multi-drug resistant bacteria [5,7]. Newly, nanotechnology has very remarkable in the pharmaceutical and biomedical field as alternative antimicrobial agent design in the view of the fact that renovation the occurrence and infective diseases of antibioticresistant strains, especially within gram-negative bacteria.…”

This study is focused on the evaluation of dependable and eco-friendly methods for the synthesis of metal nanoparticles is a significant step in the area of application of nanotechnology. One of the alternatives to obtain this purpose is to use natural techniques such as biological approach. Here, we examine biosynthesis of metallic nanoparticles using extract Proteus sp. the metal nanoparticles were successfully synthesized via reduction of silver sulfate employed extracted cell of bacterium Proteus sp. Nevertheless, the extracellular acts as a reducing agent to convert silver ion from its aqueous solution and the synthetic were formed within 2 hrs. On the other hand, scanning electron microscopy (SEM) which describes the surface morphology of bio-reduction of Ag-nanoparticles demonstrated that the spherical nature occurred through the bio-synthesis process and the particles are mostly circular and irregular in shape, UV-visible exhibit a peak at 423 nm corresponding to the plasmon of silver nanoparticle and XRD pattern was taken and presented that all peaks were indexed by hexagonal wurtzite phase (PIXcel 1D). In spite of that, the band gap energy measured (2.93 eV) and suggested strong scattering of the X-ray in the crystalline phase. Finally, we concluded that this study offers the remarkable report that biological synthetic of metal nanoparticle is helpful to avoid the negative influence of physical and chemical process that is inappropriate for medical applications.
