| Abstract | The present work describes the phytosynthesis of silver nanoparticles using fruit extract of Helicteris isora.L at ambient conditions. The formation of AgNPs was analyzed by visual observation and UV−Visible spectrophotometer. The synthesized silver nanoparticles were characterized by XRD, FTIR, FE-SEM, DLS and HR-TEM. The surface plasmon resonance spectrum of AgNPs was obtained at 435 nm, X-ray diffraction patterns reveal that the particles are crystalline form with face centered cubic structure and the HR-TEM images showed that the synthesized stable AgNPs are approximately 35-40 nm in size with distorted spherical shapes. The results showed that the fruit extract of Helicteris isora.L is sparingly good bioreductant for the synthesis of silver nanoparticles and synthesized nanoparticles active against clinically isolated human pathogens as E.coli, Pseudomonas aeruginosa, Bacillus subtilis. |
