In this paper, we study how the optical properties of gold nanoparticles and core-gold nanoshells are changed as a function of different sizes, shapes, composition and biomolecular coating with characteristic shifts towards near-infrared region, 750-900nm. We show that the optical tunability in this region can be carefully checked for particle sizes falling in the range 100-150nm. Such tunability in the range 750-900 nm is particularly important in biosystems, because the high transmittivity properties characterizing many biological tissues.

Abstract

In this paper, we study how the optical properties of gold nanoparticles and core-gold nanoshells are changed as a function of different sizes, shapes, composition and biomolecular coating with characteristic shifts towards near-infrared region, 750-900nm. We show that the optical tunability in this region can be carefully checked for particle sizes falling in the range 100-150nm. Such tunability in the range 750-900 nm is particularly important in biosystems, because the high transmittivity properties characterizing many biological tissues.
