Chennai-600061, India > Research Paper 2022 9 11 2023 06 18 Silver nanoparticles were synthesised by many methods. Our focus of interest is green synthesise method. Elettaria cardamomum extract has the potential to reduce silver nitrate resulting in the formation of AgNPs. Various characterisation techniques used were UV-Vis spectroscopy, Infrared spectroscopy, scanning electron microscope, X-ray diffraction studies and particle size analyser. The morphology, size distribution, and crystalline nature were revealed by the above studies. Phytochemical analysis of the Elettaria cardamomum husk extract was done for the presence of natural products. Further studies confirmed its ability against gram +ve and gram -ve bacteria. The gram +ve bacteria like Bacillus subtilis, staphylococcus aureaus and gram - ve bacteria like Escherichia coli and proteus vulgaris. Copyright@ International Science Community Association
