Synthesis, Characterization and Antimicrobial Activity of Abelia grandiflora Assisted AgNPs

Abstract

In past few years, wide applicability of silver nanoparticles (AgNPs) in various field attract for an approach of rapid, cost effective and eco-friendly synthesis of AgNPs that is expanding research toward biological methods. The biosynthesised AgNPs were confirmed visually by appearance of dark brown color formation in mixture and silver surface plasmon resonance band observed at 413 nm by using UV-Visible Spectroscopy A. grandiflora may be used for the green synthesis of ultra-fine nanoparticles of silver for their antimicrobial activities.

Rapid Biosynthesis Method and Characterization of Silver Nanoparticles Using <i>Zizyphus spina christi</i> Leaf Extract and Their Antibacterial Efficacy in Therapeutic Application

“…The AgNPs and aqueous extract prepared by Zizyphus spina christi L were used to evaluate antimicrobial activity against Gram positive bacteria, Staphylococcus aureus (S. aureus) and Gram negative bacteria, Echerichia coli (E. coli), Acinetobacter sp, and Pseudomonas aeruginosa (P. aeruginosa) on Mueller Hinton Agar plates by agar well diffusion method [27]. The Minimum Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC) methods for all test bacterial strains were also determined using micro plate assay method.…”

Phytoassisted synthesis of magnesium oxide nanoparticles with Swertia chirayaita

“…Suresh et al [20] explored the possibility of utilizing Nephelium lappaceum L. peel as a nontoxic, natural reducing agent for fabricating MgONPs, and the generated nanoparticles' size were in range of 60-70 nm. Previously, silver nanoparticles have been synthesized using plant materials and evaluated for antibacterial activity and were found to be impressive in their inhibitory activity against bacterial strains [21,22]. Rajgovind et al [23] studied using the heart wood of Pterocarpus marsupium for synthesizing metallic oxide nanoparticles and assessed their activity against Gram-positive bacteria and Gramnegative bacteria.…”

Biological Synthesis of Silver Nanoparticles by Cell-Free Extract ofSpirulina platensis

“…In addition, silver containing consumer products, such as colloidal silver gel and silver embedded fabrics, are now used in sporting equipment [6]. AgNPs are used in low doses for antimicrobial treatment in comparison to standard antimicrobial agents [7].…”

“…So, over the years, researchers have turned to nonpathogenic microorganisms. Among the blue-green algae (cyanobacteria), Anabaena, Calothrix, Leptolyngbya, and Nostoc ellipsosporum have been reported to synthesise intracellular gold, silver, palladium, and platinum NPs [7]. The green microalga C. vulgaris has also been reported to produce gold, platinum, palladium, ruthenium, rhodium, and iridium nanoparticles, whereas the cell-free extract efficiently produces gold and silver nanoplates intracellularly [22].…”
