Gold nanoshells consist of a silica core surrounded by a gold shell. By changing the ratio of the size of the core to the thickness of the shell, the plasmon resonance can be tuned across the visible and infrared.
- BioReady gold nanoshells are ultrabright reporter particles for molecular diagnostics. Proteins can be covalently bound to the surface of carboxyl gold nanoshells using EDC/NHS chemistry.
- NanoXact gold nanoshells are available with carboxyl, PEG and PVP surface functionalization.
