Abstract
The present study described the formation of silver nanoparticles by the extract of Alternaria sp. obtained from bark part of Calophyllum apetalum Willd. Alternaria extract have mixed with silver nitrate to synthesize silver nanoparticles. Synthesized silver nanoparticles were characterized by UV-vis spectroscopy, Scaning electron microscopy and X-Ray diffraction studies. Silver nanoparticles have acquired Surface plasmon reverberation spectra at 425nm and round shapes of the silver nanoparticles have determined by SEM analysis. X-ray diffraction studies confirm that the synthesized nanoparticles by Altenaria extract were crystalline silver. This approach is one of the primary, efficient and rapid strategies to synthesize silver nanoparticles at ambient temperature without application of hazardous agents.
