1. Miniaturized localized surface plasmon resonance biosensors
Sammanfattning : Abstract Reliable and sensitive biosensors are required for fast and accurate diagnostics. Localized surface plasmon resonances (LSPRs) in noble-metal nanoparticles possess very high refractive index sensitivity close to the metal surface and therefore constitute an attractive biosensing platform.

2. Interactions Between Localized Surface Plasmons and Molecular Resonances
Sammanfattning : Molecular plasmonics is the study of interactions between plasmonic nanostructures and molecules. It has been basis for fundamental understanding of light-matter interactions and development of many technological applications, such as biological and chemical sensing, plasmon-enhanced spectroscopies, optical switches, and plasmon-enhanced energy harvesting.

3. Coherent Plasmon-Plasmon and Plasmon-Exciton Interactions at the Nanoscale
Sammanfattning : Noble metallic nanoparticles which supports localized surface plasmon resonances, offers a variety of potential scientific as well as industrial applications. Due to a remarkable ability to confine light at nanoscale dimensions, far below the optical diffraction limit, together with an ability to detect minute changes in the local environment plasmonic nanoparticles have paved routes towards several new and intriguing techniques, promising for future applications in areas such as molecular sensing and quantum optics.
