Functional Nanoplasmonics for Chemistry and Biology
Laura Na Liu, University of Heidelberg, Germany
Functional plasmonic nanostructures with tailored configurations enable unique optical properties. This opens up many new possibilities for understanding intriguing questions in biology and chemistry. Near-field coupling between plasmonic nanostructures is very sensitive to conformational changes. This provides the opportunity for manipulation of the optical response on the nanoscale. Plasmonic nanostructures can also serve as efficient far-field to near-field transformer, converting optical radiation into strongly localized electromagnetic fields. This enables probing local dynamic changes on the nanoscale that are crucial in nanocatalysis and phase transitions of nanomaterials, where many unanswered questions abound. In my talk, I will discuss recent advances in functional nanoplasmonics. In particular, I will discuss the new aspect of developing dynamic nanoplasmonic building blocks for biology and chemistry. These plasmonic building blocks either can exhibit dynamic structural changes themselves or can be integrated with functional materials, where dynamic events take place. I will also talk about how to utilize both bottom-up and top-down nanotechniques to advance the perspective of nanoplasmonics towards synthetic plasmonic machinery as well as dynamic plasmonic devices with both tailored optical response and active functionality.
