Antibacterial potential of biosynthesised silver nanoparticles using Avicennia marina mangrove plant

Abstract

The present study was aimed to identify the antibacterial potential of biosynthesised silver nanoparticles using different plant parts (leaves, bark and root) of Avicenna marina mangrove plant. Of the selected three different parts, the leaf extract showed the maximum synthesis of silver nanoparticles. The in vitro antibacterial assay (100 lg disk-1 concentration) showed the results of maximum zone of inhibition with the E. coli (18.40 ± 0.97 mm), and minimum (10.87 ± 1.33 mm) zone of inhibition with S. aureus but the concentrations of MIC and MBC values ranged between 6.25 and 50.0 lg ml-1 between the selected bacterial strains. The FTIR results of most potent leaf extract-synthesized silver nanoparticles showed the promi

Antigenotoxic effect of green-synthesised silver nanoparticles from Ocimum sanctum leaf extract against cyclophosphamide induced genotoxicity in human lymphocytes—in vitro

“…After the incubation period, the solution was centrifuged at 12,000 rpm for 20 min, and their pellets were re dispersed in Milli Q water. The centrifugation and redispersion was repeated three times to ensure the complete separation of nanoparticles (Gnanadesigan et al 2012). Later the pellets were air dried.…”

Electrospun PCL membranes incorporated with biosynthesized silver nanoparticles as antibacterial wound dressings

“…Our previous report demonstrated that silver nanoparticles can successfully be synthesized in a facile and cost-effective way using leaf extracts of Piper nigrum (Augustine et al 2014e). Biosynthesized silver nanoparticles were reported for their excellent antibacterial activity against wide range of microorganisms (Gnanadesigan et al 2012;Kathiraven et al 2014;Netala et al 2014;Sinha et al 2014;Kumar et al 2015;Kokila et al 2015;Roy et al 2014). Antifungal activity of biosynthesized silver nanoparticles is also well studied (Kumar et al 2013;Medda et al 2014).…”

“…Recently, the plant-mediated synthesis of silver nanoparticles using Coleus aromaticus leaf (Vanaja and Annadurai 2013), living peanut seedling (Raju et al 2014), Petroselinum crispum leaf (Roy et al 2014), Citrus limon leaf (Vankar and Shukla 2012), Avicennia marina mangrove plant leaf, bark and root (Gnanadesigan et al 2012) and Justicia adhatoda L. Leaf (Bose and Chatterjee 2015) have been reported.…”
