| Using surface plasmon resonance (SPR), there are a wide diversity of systems that can be investigated ranging from biologically relevant applications to the field of material self-assembly. We have quantitatively investigated the formation of thin films and hierarchical structures using SPR spectroscopy and imaging. This research focuses on the areas of surface patterning, multilayer film deposition, and nanoparticle assembly and characterization. Methods of surface patterning enable multiplexed detection enhancing the tool's capabilities and creating a scaffold for subsequent assembly. By investigating the layer-by layer growth of metal-organic coordinated multilayers created by solution phase deposition, the processing conditions can be optimized and the fundamental growth mechanism can be further elucidated. By strategically assembling isolated or congregated nanoparticles, the optical properties of these materials and their lattice arrangements are investigated as a function of particle size, particle-particle distance, surface-particle distance, and SPR excitation wavelength. These assembled materials have potential applications in areas such as optics, molecular electronics, and nanolithography. |
