Abstract

Nanoscience and Nanotechnology are having a wide range of applications such as green chemistry, biology, medicinal chemistry, physics, materials science and engineering. Over the past few decades, nanoparticles of noble metals such as silver (bio synthesized) exhibited significantly distinct physical, chemical and biological properties. To overcome the problem of bioavailability, an effort was made to synthesize silver nanoparticles (SNP) using various concentrations of methanolic extract from the roots of Aphanamixis Polystachya by ultrasonification and were characterized by using various techniques like XRD, SEM, PSA, UV, FT-IR and EDX. Morphology and metal composition of synthesized nano particles were determined by SEM and EDAX respectively. Size of SNP were analyzed by using PSA. Further the SNP were also characterized by UV spectroscopy. A sharp peak was observed between 400nm- 420nm indicating the formation of SNP. FTIR analysis showed that the biosynthesized SNP were capped with bimolecular compounds which were responsible for reduction of silver. The bands at 3420.8 cm-1 and 2923.9 cm-1 have shown the formation of secondary amines. X-ray diffraction confirmed the predominantly spherical shape and poly dispersed SNP. It may be concluded that the methanolic extract of Aphanamixis Polystchya can be a good source for the synthesis of SNP.
