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...

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...

objectives:biofilms are communities of bacteria attached to surfaces through an external polymeric substances matrix. in the meantime, acinetobacterbaumannii is the predominant species related to nosocomial infections. in the present study, the effect of silver nanoparticles alone and in combination with biocides and imipenem against planktonic and biofilms of a. baumannii was assessed.  materi...

background: to develop a new green approach for biosynthesis of silver nanoparticles, myconanotechnology has been represented as a novel field of study in nanotechnology. in this study, we have reported the extracellular synthesis of highly stable silver nanoparticles using three species of dermatophytes: trichophyton rubrum, trichophyton mentagrophytes and microsporum canis. methods: clinical ...

The aim of this study was to evaluate gastrointestinal microbial population response and performance of broiler chickens fed organic acids and silver nanoparticles coated on zeolite under heat stress condition. In this experiment, 375 one-day old broiler chicks (Cobb 500) were randomly divided into 5 treatments containing 5 replicates with 15 birds in each replicate. Five dietary treatments wer...
