摘要：

One step phytosynthesis of highly stabilized silver nanoparticles (AgNPs) had been produced by using the extract of Piper nigrum (black pepper) as a reducing and a capping agent in aqueous medium, without the addition of any other chemicals. UV-visible (UV-vis) spectra showed the formation of AgNPs by observing the surface plasmon resonance (SPR) band at 444 nm. X-ray diffraction (XRD) analysis confirmed the formation of AgNPs with face centered cubic (fcc) structure. Fourier transform infra-red (FT-IR) spectra were used to identify the functional groups present in the biomolecules for reduction and capping of AgNPs. The electrochemical behaviour was carried out by cyclic voltammetry (CV). Oval-like morphology of the sample was confirmed by high-resolution scanning electron microscopy (HR-SEM) and high-resolution transmission electron microscopy (HR-TEM). Elemental composition was found out by the energy dispersive X-ray analysis (EDX). The antibacterial activities were carried out and revealed good results. This phytosynthetic approach is facile, inexpensive, reproducible, and eco-friendly. (c) 2014 Elsevier B.V. All rights reserved.
