Plasmonic Nanomaterials for Disease Diagnostics

In this presentation on Dec. 6th, the architecture, stability, and surface chemistry of solution-phase gold and silver nanoparticles will be correlated to nanoparticle function for improved disease treatment strategies and for the direct detection of disease biomarkers. Nanoparticle concentration, core composition, and surface chemistry will be shown to play important roles in these sensing schemes. The most rugged and reproducible nanoparticle sensors will utilize silica membrane encapsulation of gold or gold-coated silver nanoparticles. Applications related to the direct and quantitative detection of small molecules will be discussed.
