Enhancing Plasmonic Nanomaterials: Colorimetric Sensing And Sers, John Crockett

WWU Graduate School Collection

Nanomaterials, materials with at least one dimension on the nanoscale have become an area of extreme scientific interest due to their many unique properties with applications in catalysis, optics, and sensing, just to name a few. Metal nanoparticles are particularly interesting because of the interactions between light and surface electrons in the metal’s conduction band, called localized surface plasmons. In anisotropic metal nanoparticles these plasmons are especially exciting due to the highly responsive quality of the plasmonic resonance associated with their varied nano dimensions. Gold nanorods and nano dendrites in particular exhibit electromagnetic effects which are specifically associated to the …
