Silver nanoparticleswere synthesized using aqueous stem extract of Mirabilis jalapa as a reducing and stabilizing agent. This stem contains biomolecules such as alkaloids, flavonoids, triterpenes, steroid and phenolic compounds. The silver nanoparticles were characterized by UV-visible Spectroscopy (UV), Fourier Transform Infra-red Spectroscopy (FT-IR), powder X-ray diffraction (PXRD), Scanning Electron Microscope (SEM) and EDX analysis. A peak at 499 nm was obtained in UV-visible spectroscopy which indicates that the particle was polydispersed. PPXRD shows the crystalline nature of silver nanoparticles.Silver was used form long back as metallic silver, silver nitrate for the treatment of burns, wounds and many bacterial illnesses.The antimicrobial activities of silver nanoparticles were studied.
