1 Introduction Nanoscale gold materials have been widely used as sensitive optical transducers for biosensing and imaging owing to their intrinsic inertness and prominent surface plasmon resonance (SPR) properties, which are also categorized as plasmonic sensing.[1-6] The basic principle behind plasmonic sensing was established based on the plasmonic-induced electromagnetic field confined to the gold surface, which is sensitive to dielectric changes in the surrounding medium,[7-9] and where...
