DESCRIPTION:Malcolm Kadodwala\, Ph.D.\, University of Glasgow\, Glasgow (U
 K)\nBIOENGINEERING SEMINARAbstract:\nSculpted electromagnetic (EM) fields 
 created by artificially engineered metamaterials provide a route to new sp
 ectroscopic phenomena [1-3].  Thus enabling novel measurements\, such as 
 < picogram characterisation of the structure of biological materials [1]\,
  which would be impossible with conventional spectroscopic techniques.  T
 he scope for these new spectroscopic phenomena to make a significant impac
 t as: generic research tools\; medical diagnostics\; or as biosensing plat
 forms\, is limited.  Due to the fact that the metamaterials\, which are f
 ormed from periodic arrays of individual (noble metal) nanostructures\, ar
 e fabricated using electron beam lithography a costly time consuming produ
 ction method.  I present a new type of plasmonic nanomaterial\, a continu
 ous gold film that is moulded so it has nanoscale chiral indentations\, wh
 ich can be fabricated using a cheap high throughput method.  We subsequen
 tly demonstrate the application of these nano templated chiral plasmonic f
 ilms for (linear and non-linear) biospectroscopy.\n1. Hendry\, E.\; Carpy\
