Silver and gold-silver bimetallic nanoparticles find extensive applications in a wide range of areas due to many of their unique properties. The properties of these nanoparticles are highly dependent on the particle attributes like shape, size, aspect ratio, surface chemistry, etc. It is important to understand the relationship between particle property and their attributes in order to design the nanostructures with optimum performance for many of the applications. We synthesized a library of monodisperse silver and silver-gold bimetallic nanoparticles with independent adjustable shape, size and surface chemistry. The optical and antibacterial properties of these particles are investigated. The systematical study of the relationship between nanoparticle property and structure paves the way to nanomaterials by design.
