Abstract
Silver nanoparticles (AgNPs) were biosynthesized at room temperature under sunlight irradiation, using the extract of Jasminum subtriplinerve Blume (JS) leaf as a reducing agent and also stabilizers. The obtained AgNPs were thoroughly characterized by UV–Vis Spectroscopy, X-ray diffraction (XRD), high-resolution transmission electron microscopy (HR-TEM), Fourier-transform infrared spectroscopy (FT-IR) and their antibacterial property was evaluated on five types of bacteria by implementing the minimum inhibitory concentration test (MIC) and the zone of inhibition test. No antibacterial activity was observed in the JS extract compared to the AgNPs; meanwhile, AgNPs exhibited effective antibacterial activity against all bacteria with an average diameter of inhibition zones of over 10.0 mm and the minimum inhibitory concentration of 33.08 µg/mL (higher inhibiting activity against gram (−) bacterial than that of gram (+) bacterial).
