Antibacterial and cytotoxic activities of a green synthesized silver nanoparticles using corn silk aqueous extract

Biosynthesized silver nanoparticles using Caulerpa taxifolia against A549 lung cancer cell line through cytotoxicity effect/morphological damage

“…It has enormous activity with naturally renewable, cost-effective ( Sahoo et al, 2020 , Batool et al, 2019 , Lakhan et al, 2020 , Vijaya Anand et al, 2019 , Ebrahimzadeh et al, 2020 , Ramesh et al, 2018 ). Recent years, considerable studies are going on Ag NPs synthesis through biological synthesis using plant extract, microbes, sponge associated extract, marine organism mediated Ag NPs and some other marine and terrestrial microorganisms ( Shah et al, 2020 ) Among these, the plant associated Ag NPs was very high due to the increased biological properties ( Li et al, 2020 ). It has the absorption capacity and utilizes the some important chemical substituents from plants.…”

Effect of Silver Nanoparticles on the Morphology of Toxoplasma gondii and Salmonella braenderup

“…e results obtained by the exposure of Salmonella braenderup and the Toxoplasma gondii oocysts to AgNPs showed pronounced morphological changes, which is an indicator of rupture in the bacillus membrane or in the wall of the oocyst, and this can be directly related to viability and the potential for infection of both microorganisms. Also other studies showed antibacterial activity against Gram-negative bacteria such as Salmonella and E. coli and Gram-positive bacteria such as Staphylococcus aureus and Bacillus subtilis, suggests that the AgNPs bind to the cell wall of the bacteria, causing membrane permeability and damaging vital structures of the bacteria, such as proteins, DNA, and enzymes [37]. Also Singh et al reported that AgNPs showed antimicrobial activity against different species of bacteria, including Salmonella enterica [38], and AbuDalo also showed that AgNPs had an antibacterial effect against pathogens such as Salmonella enterica, Escherichia coli, and Staphylococcus aureus [34].…”

An Updated Review on Silver Nanoparticles in Biomedicine

“…Strong bactericidal or bacteriostatic effects against E. coli were also reported for AgNPs biosynthesized with gum kondagogu (4.5 ± 3.1 nm) [ 118 ], Arisaema flavum extract (5–8 nm) [ 119 ] and Polygonatum graminifolium extract (3–15 nm) [ 120 ], but also for nanoparticles capped with PVP (16 ± 2 nm) [ 121 ], pectin (8–13 nm) [ 122 ] and chitosan (>20 nm) [ 123 ]. AgNPs biosynthesized with corn silk extract (10–30 nm) [ 124 ], belladonna tincture (15–20 nm) [ 125 ], thyme extract (75 nm) [ 126 ] and nanosilver bioreduced by Bacillus subtilis (3–20 nm) [ 127 ] and Lactobacillus brevis (45 nm) [ 128 ] showed pronounced antibacterial effects against S. aureus .…”
