Our research in brief
Things change at the nanoscale! New phenomena arise, making nanoscale objects behave differently than macroscale objects. These new phenomena can be used in a plethora of novel applications and devices, which explains the great hope in nano to provide entirely new technologies rather than only a way to make things smaller.
An excellent example of a nanophysical phenomenon is the colour of gold nanoparticles. In contrast to large gold objects, gold nanoparticles are red and shiny. This is due an extraordinary strong interaction between light and metallic nanostructures. Light of certain colours is scattered and absorbed by the structure through excitation of collective oscillations of the metal electrons. These oscillations are called plasmons or nanoplasmons. Apart from being shiny, plasmonic structures can be used to manipulate light at the nanoscale, to form highly intense hot spots with strong electromagnetic fields or as nanoscale heat source.
In our research we utilize unique optical properties of plasmonic metal nanostructures in conceptually new applications. In particular, we explore hybrid plasmonic devices based on electrically and ionically conducting polymers. By in this way bridging the fields of nanoplasmonics and organic electronics, we aim to provide novel energy harvesting concepts like, solar water splitting and thermoelectrics. Moreover, we have contributed significantly to the field of plasmonic sensing and by the development of the plasmonic nanopore for single-molecule DNA analysis.
Related areas that we are interested in include nanofabrication, organic electronic devices, photoconductive materials, and nanofluidics.
