Abstract:
Abstract The green synthesis of silver nanoparticles (AgNPs) from Psidium guajava leaf extracts, characterization and bioactivity is reported. The optimum synthesis conditions were achieved after 2 h at a temperature of 80 oC in 11 mM silver nitrate and 8 mL Psidium guajava leaf extract amount. High throughput characterization such as ultraviolet –visible (UV-Vis) spectrophotometer, Fourier transform infrared spectrophotometer (FT-IR), Scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive X-ray analysis (EDAX) spectrophotometer were used to confirm the synthesized silver nanoparticles. The 20 nm spherical AgNPs were evaluated as antibacterial agents. Antibacterial studies of synthesized determined by disc diffusion susceptibility test. AgNPs were effective against Staphylococcus aureus and Escherichia coli bacteria with the highest inhibition zone of 20 mm obtained and MIC value of 7 mg/ml against E. coli and 11 mg/ml against S. aureus obtained.
