We report a facile, one pot, green synthetic process for developing size- and shape-controlled metallic and bimetallic nanomaterials, as well as studies to understand their interactions under various environmental conditions. Monodisperse metallic and bimetallic nanoparticles were fabricated at room temperature using environmentally friendly reaction conditions.  These nanostructures were produced with controlled size, shape, composition, crystallinity, and structure (i.e. hollow vs. solid). Controlling the morphology of metal nanoparticles is essential toward understanding their structure-function properties especially under varying temperature, pH and ionic strength conditions.   Shape control of metal nanomaterials is important because it allows one to tune their optical, magnetic, and catalytic properties.  The synthesis of well-defined anisotropic nanoparticles under green reaction conditions is important toward advances in nanoscale synthesis. Characterization of the nanoparticles was carried out using high resolution transmission electron microscopy (HRTEM), x-ray diffraction (XRD), small angle electron diffraction (SAED) and energy dispersive spectroscopy (EDS).
