Abstract

Abstract This study reports a single-step, fast and eco-friendly procedure for preparing silver nanoparticles from silver nitrate solution using fruit extract of Benincasa hispida along with the study of its ability for fast detection of hydrogen peroxide. Silver nanoparticle formation was confirmed by scanning the reacting mixture at regular intervals using UV-Vis spectroscopy. The X-ray diffraction pattern of the dried nanoparticles revealed the information about different phases and crystallinity of biogenic Ag nanoparticles. The size, shape and morphology of the nanoparticles were studied by transmission electron microscopy. Fourier transform infrared spectroscopy was performed to identify organic molecules that reduced and capped the colloidal particles in the reacting medium. Furthermore, the H 2 O 2 detecting ability of these biogenic silver nanoparticles was explored and the Ag nanoparticles were found to detect H 2 O 2 instantly.
