Biosynthesis of Silver Nanoparticles by Using Papaya Fruit Extract

Alvakonda Narayanamma

Abstract: Nanotechnology in the latest contest is acquiring its potential due to its capability of changing metals into their nanoparticles. There are few studies on the nanoparticles in plants. Our present research is to investigate on the novel synthesis, of biodegradable silver nanoparticles using fruit extract of papaya. In this green synthesis we used papaya fruit extract which acts as a natural reducing agent to synthesize biodegradable silver nanoparticles by using Acrylamide (AM). The silver nanoparticles were synthesized by reducing AgNO3 with fruit extract from papaya. The hydrogel of fruit extract characteristic color is changed from pale yellow to dark brown by reduction. Characterization of newly synthesized biodegradable silver nanoparticles was analyzed by using UV visible spectroscopic technique, Fourier transform infrared spectroscopy (FTIR), X-Ray Diffraction (DSC), Thermo gravimetric analysis (TGA), XRD, Scanning electron microscopy (SEM), and Transmission electron microscopy (TEM). In the present study 10 nm size nanoparticles are synthesized. These nanoparticles have antimicrobial applications, especially against Bacillus and Escherichia coli.
