The Silver nanoparticles are well-known for their antimicrobial, anti-inflammatory wound healing abilities. We synthesized Silver nanoparticles using chemical reduction method and the formation of the silver nanoparticles was characterized by UV-Vis absorption spectroscopy, FT-IR and SEM techniques. The minimum inhibitory concentration of the synthesized nanoparticles was determined for both gr...

Background: Developing effective methods for the synthesis of bio-compatible and non-toxic nanoparticles is the main goal of nanotechnology. In the most chemical methods, a chemical reducing agent is used to reduce metal ions. But, in chemical methods, the stability of nanoparticles is controversial and synthesis in large sizes is much more difficult. Moreover, there is an incr...

In this experiment, green-synthesized silver and gold nanoparticles were produced rapidly by treating silver and gold ions with an extract of Memecylon umbellatum leaf. The reaction process was simple and easy to handle, and was monitored using ultraviolet-visible spectroscopy. The effect of the phytochemicals present in M. umbellatum, including saponins, phenolic compounds, phytosterols, and q...

to identify the larvicidal activities of silver nanoparticles synthesized with acanthus ilicifolius (a. ilicifolius) leaf extract against the larvae of armigeressubalbatus and aedesaegypti. in vitro larvicidal activities such as lc50 and lc90 were assessed for the a. subalbatus  and ae.aegypti larval species. further, characterization using different techniques such as uv, sem,edax, xrd and fti...

Background: As nanoparticles have multiple applications, there are many different methods for the production of silver nanoparticles (Ag-NPs). Recently, plants are being used in the synthesis of nanoparticles, due to their cost- effectiveness and eco-friendliness approach. In this study, the biosynthesis of silver nanoparticles using extract of Citrus aurantium for its antimicrobial properties ...

Background: Because most bacteria responsible for hospital infections are resistant to common antibiotics, the tendency to produce effective and nontoxic anti-microbial drugs have increased. Therefore, it is attempted to substitute antibiotics with natural products, such as nanoparticles and plant extracts. The aim of this study was to investigate the synergistic antibacterial effects of silver...
