Project title: Nanostructures for Biosensing Applications

Project Description:

Student without prior knowledge of plasmonic effects would normally be able to take on this project, as the aspect of plasmonics will be guided.  


Surface plasmons are surface electromagnetic waves that propagate parallel to the metal/dielectric interface.  The excitation of surface plasmons by light is known as surface plasmon resonance (SPR).  It is well known that plasmon oscillations are very sensitive to the change of the medium (e.g. air, water, or other bio-substances) in contact with the metal layer.  So in some applications the phenomenon of SPR has been adopted as bio-sensors (e.g. for sensing DNA).  The research can also be utilizing the localized SPR (LSPR) effect, or surface-enhanced Raman scattering effect, for which single molecule detection could be possible. The work can be experimental, simulation or both.
