My key role is to play a theoretician working coherently with experimentalists in an EPSRC-sponsored research project, based at Imperial College London, which also includes the participation of overseas academic and industrial partners. This advanced ‘nanoplasmonics’ project is devoted to the creation of novel optical metamaterials based on electro-tuneable self-assembly of simple metallic or composite plasmonic nanoparticles at liquid–liquid and solid–liquid interfaces. These metamaterials could be targeted on detection of trace amounts of hazardous molecules (e.g., illegal substances, environmental pollutants, bacteria or viruses) as well as on creation of electrovariable nanophotonic devices such as mirrors, windows and optical switches, just to name a few. The research project, thus, offers a unique blend of experience in pursuing top-notch theoretical research at the cutting edge topics of nanoscience and specifically nanoplasmonics within a world-class multidisciplinary academic environment.
