Nanoscale Biomolecular Detection Limit for Gold Nanoparticles Based on Near-Infrared Response
Figure 1
(a) Schematic sketch of a gold nanoshell, and are the core and shell radii, and the complex refractive indices for the core, shell, and the surrounding medium are , , and , respectively. (b) The same gold nanoshell with a biomolecular absorbed coating layer. Note that the shell radius is defined as the total radius minus the core radius.
