Abstract
Silver nanoparticles play an important role in controlling mosquito population as well as multidrug resistant pathogens. An aqueous extract of Pedalium murex L. was used for the synthesis of silver (Ag) nanoparticles and its antibacterial activity. The green synthesis of nanoparticles in plants is cost-effective and eco-friendly approach. To identify the compounds responsible for the reduction of silver ions, the functional groups present in plant extract were investigated by Fourier Transformation Infra Red Spectroscopy (FT-IR) and characterization of nanoparticles was done using standard analytical methods. UV-visible spectrum of the aqueous medium containing silver nanoparticles showed absorption peak at around 350-600 nm. The compounds observed from FT-IR spectra are correlated with the reduction and capping material of silver nanoparticles. The observed results suggested that the bioactive compounds present in Pedalium murexL, was found to exhibit a significant inhibitory activity against selected pathogens.
