results the results revealed the formation of spherical silver nanoparticles with an average size of 10 nm. moreover, concentration of snps in a 25 ml sample containing both snps and plant extract biomass was 2.934 mg/l on average. serial microdilution test showed that snps at the concentration of 50 μg/ml can inhibit growth of the pathogen. conclusions the present study extends the existing li...

silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  the present study aimed at the comparative study of silver nanopartic...

The present study focused on the synthesis of silver nanoparticles using the aqueous extract of Ulva flexousa (green seaweed). Ten ml of the aqueous extract of alga was mixed with 90 ml of 1mM aqueous AgNO3 solution for reducing of Ag+ ions. The synthesized silver nanoparticles were characterized by UV-Vis spectra, XRD (X-ray diffraction), TEM (Transmission electron microscopy) and FT-IR (Fouri...

silver nanoparticles (agnps) are amongst the most investigated materials in nanotechnology in view of their unique physio-chemical features and applications in restorative science. their progressive usages in different fields of science besides some predominant restrictions with conventional methods for their synthesis have demanded analysts to discover green courses for their creation. biologi...

in the present study, a simple, fast and eco-friendly biosynthesis of silver nanoparticles (agnps) using   mentha langifolia leaf extract as the reducing agent was investigated. nanoparticles forming were indicated by the color changes in solution and were confirmed by uv-vis spectrum, ft-ir analysis and scanning electron microscopic (sem) micrograph. the average particle size of produced agnps...
