This presentation will be focused on our recent progress in the fabrication of metallic nanostructures with tunable plasmonic properties by using colloidal synthesis and self-assembly methods.  We will first discuss the tailored synthesis and shape evolution studies of plate-like silver nanostructures, with particular emphasis on a unified set of colloidal approaches for the synthesis of silver nanoplates with well-controlled size and shape, high stability, and tunable surface plasmon band from ~400 nm to IR.  Second, we will discuss the tuning of the optical properties of metallic nanostructures through manipulating the surface plasmon coupling using a number of self-assembly approaches.  In particular, the self-assembly of charged gold nanoparticles into linear chain structures in solution enables a class of dynamically tunable plasmonic structures.
