Plasmonic nanostructures have been incorporated in biosensors and organic photovoltaics to improve their performance. Label-free detection of specific target analytes and differentiating them from interfering background effects present a crucial but challenging task in the complex multi-component solutions commonly encountered in biomedical and environmental sensing applications. An overview of recent progress on circular plasmonic interferometric biosensors will be presented. Organic semiconductors used as light-harvesting and charge transport materials in photovoltaic devices have poor electrical conductivity and short exciton diffusion length. Solar cells based on these materials fabricated over large area flexible or rigid substrates are very promising but do not absorb enough solar light. Incorporation of metallic plasmonic nanostructures in these devices offers an attractive means to dramatically increase the device optical thickness while maintaining its physical thickness very thin. This leads to a dramatic increase in the device short-circuit current density and power conversion efficiency. An overview of recent progress on plasmonic and nanophotonic enhanced solar cell devices will be presented.<br/>
