DESCRIPTION:Since Tang and Cohen’s demonstration of superchiral electrom
 agnetic near fields\, the plasmonics/metamaterial community have keen to u
 nderstand such fields when excited using metallic nanostructures and to ex
 plore their applications in a variety of disciplines. Over the past 10 yea
 rs\, I have been involved in some of this work where our focus lay on the 
 ability to use such fields to detect structural properties of biomolecules
  using plasmon resonance changes. Recently\, we have been able to implemen
 t similar concepts to perform surface enhanced Raman spectroscopy (SERS) t
 hat is sensitive to chirality\, enabling a unique new way of enantiospecif
 ic recognition. In my talk\, I will summarise our developments with chiral
  plasmonic sensing followed by its applications in multiplexed biosensing 
 and SERS detection of enantiomers using similar principles and sensing sub
 strates.
