Abstract
Plasmonic nanostructures, comprised of metallic nano-particles, are ideally suited for many sensing applications ranging from chemical to biological. Plasmonic structures offers a high sensitivity to environmental changes as they have the ability to confine light to an extremely small space which in turn helps detect particles of equivalent size. Herein, we present a design for a coupled metallic nano-particle array that offers an improved sensitivity that is higher than that of conventional nanostructures. The proposed sensing scheme makes use of coupled optical resonances between nanoparticles to enhance the interaction between the nanoparticles and the environment. This design can be integrated with an on-chip laser and detector in order to realize a fully integrated lab-on-a-chip system. These integrated devices could have various applications relevant to the biomedical industry in establishing a pervasive sensing technology that is low-cost, accurate and offers quick medical diagnostics.
