Nanomaterials possess novel properties as the size of particles decreases to nanoscale. To understand and exploit these unique properties, we need to develop effective strategies to synthesize nanoparticles with controllable size, shape, and composition. In this presentation, we focus on synthesis of gold and silver nanoparticles due to their unique optical properties and ease of fabrication. This presentation describes results of microwave-assisted irradiation aimed at developing the ability to control the size and composition of gold and silver nanoparticles. We used laboratory microwaves which are becoming common tools in research and teaching laboratory. Compared to conventional means of heating, microwaves provide shorter reaction times and better reproducibility. The key component of microwave-assisted irradiation is that nanoparticles synthesis can be completed within minutes thereby saving time and energy. The reduction in reaction time makes it possible to complete the synthesis and acquire spectroscopic data for characterization of the products within the same laboratory period. An array of characterization techniques such as transmission electron microscopy and UV-Vis spectrophotometry were used. Most of the synthesis work was performed by High School students during the Hampton University's NanoHU summer research program.<br/>
