Abstract: Silver nanoparticles have received attention due to their physical, chemical and biological properties and were thus applied in numerous biomedical applications. In this study we have done the green synthesized silver nanoparticles using Hibiscus flower extract. The prepared nanoparticles were characterized by using analytical techniques such as FT-IR, UV-visible, AFM. The metal nanoparticles were studied by UV-visible absorption spectroscopy studies. The stretching and bending vibrations of metal oxide are characterized by using FT-IR techniques. The particle sizes and morphology of nanoparticles were determined through Atomic force Microscope (AFM). The silver nanoparticles was found to be highly active towards antioxidant studies
