Abstract: Metal nanoshells are a new form of optically active nanoparticle with a tunable optical polarizability capable of spanning the visible to the midinfrared region of the spectrum. Nanoshells have found utility in a variety applications ranging from photo-oxidation inhibition in photoluminescent polymer films, optically triggered drug delivery systems, optomechanical materials, whole blood immunoassays, Raman sensors that can be optimized to specific pump laser wavelengths, and thermal ablative therapy for cancer. Despite the many advances in nanoshell-based technologies, nanoshell synthesis is a multi-step process possessing many parameters that have yet to be optimized. A critical step in nanoshell fabrication is the functionalization of the silica core with amines. It is believed that the extent of amine coverage detennines the continuity of the resulting metal shell. This study therefore examines the resultant surface coverage of amines on these silica cores, the size of the functionalized cores, and the quality of the resultant nanoshell after reacting the cores with different concentrations of aminopropyltriethoxy silane (APTES)--the amine precursor solution. These studies found that increasing the amount of APTES does increase the surface concentration of amines, does not increase the size of the functionalized core, and does provide for a higher quality nanoshell to be formed.
