Metal nanoshells having a dielectric core with a
thin gold layer are generating new interest due to the unique
optical, electric and magnetic properties exhibited by the
local field enhancement near the metal – dielectric core
interface. These nanoshells possess strong, highly tunable
local plasmon resonances with frequencies dependent
upon the nanoshell shape and core material. These
unique characteristics have applications in biosensing,
optical communication and medicine. In this paper, we
developed a theoretical, numerical and experimental
approach based on a scanning near optical microscope to
identify nanoshells inside mouse cells. Taking advantage
of the characteristic near-infrared transparency window
of many biological systems, i.e. the low light absorption
coefficient of biological systems between 750−1100 nm,
we were able to identify a 100−150 nm diameter barium
titanate-gold nanoshell inside the h9c2 mouse cells.
