Abstract
The ability to reproducibly and accurately control light matter interaction on the nanoscale is at the core of the field of optical biosensing enabled by the engineering of nanophotonic and nanoplasmonic structures. Efficient schemes for electromagnetic field localization and enhancement over precisely defined sub-wavelength spatial regions is essential to truly benefit from these emerging technologies. In particular, the engineering of deterministic media without translational invariance offers an almost unexplored potential for the manipulation of optical states with vastly tunable transport and localization properties over broadband frequency spectra. In this paper, we discuss deterministic aperiodic plasmonic and photonic nanostructures for optical biosensing applications based on fingerprinting Surface Enhanced Raman Scattering (SERS) in metal nanoparticle arrays and engineered light scattering from nanostructured dielectric surfaces with low refractive index (quartz).
