Abstract: Accurate control of size, composition, morphology,and stability, and the use of environmentally friendly procedures are highly desirable for the synthesis of nanoparticles. Here is a report on the use of Vitis californica leaf broth for the synthesis of gold nanoparticles.The morphology of the particles formed consists of a mixture of gold nanotriangles and spheres with fcc (111) structure. At lower concentrations of the extract, formation of triangular-shaped particles is found to dominate, while at higher concentrations, almost spherical particles alone are observed. The investigations made on the surface enhanced Raman scattering activity of these nanoparticles using 2-aminothiophenol and crystal violet as probe molecules are discussed in detail. The synthesized nanoparticles displayed efficient antibacterial activity against the tested gram-negative bacterium Escherichia coli and gram-positive bacterium Staphylococcus aureus
