Abstract
Green synthesis of nanoparticles from plant materials opens a new scope in nanobiotechnology and discourages the use of
expensive toxic chemicals. The aim of this study was to develop and optimize a method for the synthesis of Silver Nanoparticles
(AgNPs) from ethanolic extracts of fruits of Annona muricata as well as to characterize the green synthesized
AgNPs. AgNPs were synthesized via AgNO3
solution. The AgNPs were characterized using spectroscopy and microscopy
techniques. The formed AgNPs had an absorption maximum of 427 nm and were stable under different temperature, pH and
storage conditions. Fourier Transform Infrared Resorption spectroscopy revealed the functional groups responsible for the
synthesis and stabilization of the AgNPs. Scanning Electron Microscopy analysis revealed a spherical nature of the AgNPs.
Energy Dispersive X-Ray spectroscopy showed presence of Ag, Cl, Ca, and Si with Ag having the highest composition at
80%. X-ray diffraction and dynamic light scattering revealed a crystalline nature of AgNPs with an average size of 60.12 nm
and a polydispersity index of 0.1235 respectively. Transmission Electron Microscopy analysis further confirmed the crystalline
and spherical nature of the AgNPs. In this article, an efficient, eco-friendly and low-cost method for the synthesis and
recovery of stable AgNPs using ethanolic extracts of Annona muricata fruits as both reducing and capping agents has been
reported. The synthesized AgNPs could have many biomedical and clinical applications.
