Abstract: Background: Synthesis of silver nanoparticles (AgNPs) using green plants is important for biocompatibility, reduced hazards, policy and eco-friendliness. Materials Methods: In this study, a leaf extract Solanum indicum associated AgNPs were used to examine larvicidal properties other biological activities. AgNP forms characterized with scanning electron- microscopy (SEM), Fourier Tran...
The Present Bio-synthesis is an efficient, fast, cheap, nontoxic, simple and eco-friendly protocol for silver nanoparticles synthesis, which is more beneficial than commonly used physiochemical methods. Here in silver nanoparticles are biosynthesized using Citrus sinensis var. Kozan yerly fruit juice as reducing and stabilizing agent. The X-ray diffraction (XRD) pattern confirms the crystalline...
The frontiers of nanomedicine are consistently being challenged by the gradually expanding knowledge properties nanoparticles. Toward this end, biogenic synthesis silver nanoparticles utilizing natural compounds in plants as reducing and capping agents grabbed considerable attention, lieu synthetic hazardous physical chemical techniques. Green (AgNPs) has proven safe effective treating type 2 d...
Biogenic reduction of silver ion to base metal is quite rapid, readily conducted at room temperature and pressure, and easily scaled up. Synthesis mediated by plant extracts is environmentally benign. The objective of this study was to synthesis of silver nanoparticles (Ag-NPs) using leaves aqueous extract of Nasturtium Officinale R. Br. (NO) and its antibacterial activity. X-ray diffraction (X...
silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles. the present study aimed at the comparative study of silver nanopartic...
conclusions: the results showed that silver nanoparticles have an antimicrobial effect against intramacrophage b. abortus 544. results: the well diffusion agar study showed that silver nanoparticles have an antimicrobial effect on b. abortus 544. the mic and mbc of silver nanoparticles against b. abortus 544 were; 6 ppm and 8 ppm, respectively. the silver nanoparticles showed antibacterial effe...
interaction of chrysosporium sps. and aspergillus sps. with aqueous agno3 was investigated for synthesis of silver nanoparticles. biological reduction and extracellular synthesis of silver nanoparticles in 28 hour at 270c and ph 5.6 was done. the nanometallic dispersion was characterized by surface plasmon absorbance measuring at 424 – 530 nm for ag nanoparticles. high resolution transmission e...
With the growing awareness for need of sustainable environment, importance synthesizing and application green nanoparticles has gained special focus. Among various metal nanoparticles, silver (AgNPs) have gain significant attention. AgNPs are synthesized conventionally by physical chemical methods using chemicals such as reducing agents, which hazardous to environment due their toxic properties...
Biogenic gold nanotriangles and spherical silver nanoparticles were synthesized by a simple procedure using Aloe vera leaf extract as the reducing agent. This procedure offers control over the size of the gold nanotriangle and thereby a handle to tune their optical properties, particularly the position of the longitudinal surface plasmon resonance. The kinetics of gold nanotriangle formation wa...
