| 概 要 |
Sculpted electromagnetic (EM) fields created by artificially engineered metamaterials provide a route to new spectroscopic 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. The scope for these new spectroscopic phenomena to make a significant impact as: generic research tools; medical diagnostics; or as biosensing platforms, is limited. Due to the fact that the metamaterials, which are formed from periodic arrays of individual (noble metal) nanostructures, are fabricated using electron beam lithography a costly time consuming production method. I present a new type of plasmonic nanomaterial, a continuous gold film that is moulded so it as nanoscale chiral indentations, which can be fabricated using a cheap high throughput method. We subsequently demonstrate the application of these nano templated chiral plasmonic films for (linear and non-linear) biospectroscopy.
