Abstract

In this paper, we report on the development of a fully integrated biochip that uses surface plasmons to control all aspects of a fluorescence assay. This includes both excitation and emission characteristics and so in addition to the fluorescence enhancement/quenching also control of the spatial location, beam direction and polarization of the excitation light. These effects are investigated with both bare fluorescent molecules and quantum dot-labeled cells
