Nanoparticle Synthesis

The novel properties, minute size, large surface area-to-volume ratio, and ability to be uptaken by bioentities all make nanoparticles of immense interest in our group. As noble metals (e.g., Au) are reduced in size to several tens of nanometers a new energy absorption band is observed - the surface plasmon oscillation - which makes these nanoparticles attractive spectroscopic labels (e.g., Extrinsic Raman Labels, ERLs). Further, through shape manipulation by molecularly driven atomic assembly, we can alter the surface Plasmon oscillation of these particles. To understand and use these novel nanostructures effectively we strive to characterize both their general and interfacial properties.
