Silver nanoparticles (AgNPs) were successfully synthesised from aqueous silver nitrate using the extracts of Arachis hypogaea peels. The synthesised SNPs were characterized by Fourier transform-infrared spectroscopy analysis, X-ray diffraction, transmission electron microscopy analysis and high-resonance scanning electron microscopy, and energy dispersive(More)
Vector control is facing a threat due to the emergence of resistance to synthetic insecticides. Insecticides of plant origin my serve as an alternative biocontrol technique in the future. The aim of the present study was to evaluate the larvicidal activity of fractions and compounds from the whole-plant methanol extracts of Leucas aspera on the(More)
Phytochemicals represent a rich resource for the discovery of novel pesticides that are effective, cheap and environmentally safe. The main targeted mosquito vectors Aedes aegypti and Anopheles stephensi cause serious human diseases. The chloroform, acetone, ethanol, methanol and aqueous peel extracts of Arachis hypogaea were studied for its larvicidal(More)
Microbe mediated synthesis of silver nanoparticles (AgNPs) constitutes a reliable, eco-friendly approach ameliorating green-chemistry principles. In this study, stable silver nanoparticles were synthesized by exposing aqueous silver ions to extracellular exudates of B. subtilis A1 under optimized laboratory conditions. The synthesized nanoparticles were(More)
