Abstract

In this contribution optical properties of new metallic nanoparticles for biomedical applications are investigated. These particles consist of a pair of opposing gold prisms with asymmetric dielectric holes. In this configuration the structure exhibits multi-resonant behavior in the Visible and Near Infrared Region, useful tool for multi-sensing platform based on local refractive index measurements. The electromagnetic properties of the structure are evaluated in terms of extinction cross-section through proper full-wave simulations. The sensitivity performances for the local refractive index variation are discussed. The obtained results show that the proposed particles could be efficiently applied for sensing applications.
