ABSTRACT
Biological methods are considered safe and ecologically sound for the nanomaterial fabrication as an alternative to conventional, physical and chemical methods. Thecauliflowerbroth was found to be a suitable plant source for the green synthesis of silver nanoparticles. In the process of synthesizing silver (Ag) nanoparticles we observed a reduction of silver ions leading to the formation of stable crystalline silver nanoparticles in the solution. Water-soluble organics present in the plant materials were mainly responsible for the reduction of silver ions to nano-sized Ag particles. Energy dispersive X-ray spectrometers (EDAX), UV-Vis spectroscopy analysis of these particles, XRD and Particle size distributions results confirmed the presence of nano-crystalline Ag particles. The antibacterial effect of silver nanoparticles produced in this study was studied against two human pathogens Escherichia coli (E. coli) and Staphylococcus aureus (S.aureus).
