Antimicrobial activity of Silver Nanoparticles synthesized by using Medicinal Plants
Biologically synthesized silver nanoparticles (SNPs) are being widely using in the field of medicine. Extracellular biosynthesis of silver nanoparticles was carried out by using medicinal plant extracts for the reduction of aqueous silver ions in short period. The silver nanoparticles formation was confirmed by the colour change of plant extracts (SNPs) and further confirmed with the help of UV...
متن کاملAntimicrobial activities of silver nanoparticles synthesized from Lycopersicon esculentum extract
Background: It has been known for quite some time now that silver nanoparticles (AgNP) can inhibit microbial growth and even kill microbes. Our investigation reports the antimicrobial activity of AgNP against a model bacterium, Escherichia coli. Methods: The aqueous extract of Lycopersicon esculentum (red tomato) was used for the rapid synthesis of AgNP, which is very simple and eco-friendly in...
متن کاملSilver Nanoparticles as a Smart Antimicrobial Agent
In modern medicine the resistance to conventional antibiotics is becoming a serious concern due to high instances of mortality. Several metallic nanoparticles are suggested as promising anti-microbial agents against multidrug-resistant bacteria and some viruses. Among the nanoparticles mentioned, we review the recent finding which demonstrate the impact of silver nanoparticles on antimicrobial ...
متن کاملAntimicrobial effects of silver nanoparticles.
The antimicrobial effects of silver (Ag) ion or salts are well known, but the effects of Ag nanoparticles on microorganisms and antimicrobial mechanism have not been revealed clearly. Stable Ag nanoparticles were prepared and their shape and size distribution characterized by particle characterizer and transmission electron microscopic study. The antimicrobial activity of Ag nanoparticles was i...
متن کاملChirality of silver nanoparticles synthesized on DNA.
Silver nanocrystals grown on a poly(dG)-poly(dC) double stranded DNA scaffold displayed circular dichroism at their surface plasmon excitation band. This chiral plasmon signature was not observed in a control experiment where silver nanocrystals of similar size were produced without the DNA template and adsorbed to the DNA. It is concluded that the DNA templated Ag nanocrystals had a preferred ...
