Biosynthesis of metal nanoparticles using plant extract has received much attention due to its eco-friendly nature. The present study elucidates the green synthesize of Silver nanoparticles (AgNPs) from methanolic extract of Coleus Vettiveroids –an endemic species. The synthesis of AgNPs was confirmed by UV-visible spectrometry at 416 nm. Further, biosynthesized nanoparticles were characterized...

Silver nanoparticles in the form of silver based chemicals trace back their origin to time immemorial since the dilute forms of silver nitrate were used in place of antibiotics before they dominated the field of medicine. But, it has now become necessary to explore the anti-microbial properties of silver based chemicals again due to the microbes gaining resistance against the wide range of pres...

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 ...

biosynthesis of silver nanoparticles with small size and biostability is very important and used in various biomedical applications. in the present work, we describe the synthesis of silver nanoparticles (ag-nps) using seed aqueous extract of olea europaea (oe) and its antibacterial activity. uv–visible spectroscopy, x-ray diffraction (xrd), transmission electron microscopy (tem), scanning elec...

The use of nanoparticles in sensing is attracting the interest of many researchers. The aim of this work was to fabricate Acacia gum-stabilised silver nanoparticles (SNPs) using green chemistry to use them as a highly sensitive and cost-effective localised surface plasmon resonance (LSPR) colorimeter sensor for the determination of reactive oxygen species, such as hydrogen peroxide (H2O2). Silv...
