A simple and eco-friendly biosynthesis of silver nanoparticles (AgNPs) is reported here using apple fruit extract as reducing and capping media under microwave irradiation. AgNPs were characterized by UV–visible spectroscopy, XRD, FT-IR and TEM. The kinetics of reduction of aqueous silver ions during reaction with the apple fruit extract were monitored with the help of UV-visible spectroscopy. The XRD pattern of AgNPs was found agreeing with the fcc structure of Ag metal. Further, where TEM analysis exhibited formation of spherical shaped nanoparticles in the range of 10–45nm; FTIR analysis was carried out to identify the functional groups which were responsible for reduction/capping of AgNPs and conclude that the characterized AgNPs carry the potential for adoption in various medical and industrial applications.
