Plasmonic devices and meta-materials for bio-sensing and bioimaging
The optical excitation of surface plasmons results in spatial confinement of electromagnetic fields. These confined fields can interact with nearby molecules in a very interesting way, and we are looking into using these surface plasmons generated from nanoscale meta-materials that lead to extraordinary properties in light field manipulation for bio-sensing and bioimaging applications.
