The ZnCuNiAgO composites were synthesized through green method using Chaetomorpha antennina seaweed extract. From the XRD patterns of biosynthesized ZnCuNiAgO composites exhibited mixed hexagonal/monoclinic/cubic structure. FESEM image shows that synthesized ZnCuNiAgO composites was formed rack like structure. From the FT-IR spectra, the M-O stretching bands observed at 574 and 465 cm-1forZnCuNiAgO composites. Optical studies was determined by UV-Visible and PL spectra. In order to explore new strategies to identify and develop the next generation of drugs or agents to control a bacterial infection, the antibacterial properties of the ZnCuNiAgO composites was examined by Gram positive and Gram negative strains.
