Plasmonics in Biology and Plasmon-Controlled Fluorescence [PDF]
Plasmonics, 2006 Fluorescence technology is fully entrenched in all aspects of biological research. To a significant extent, future advances in biology and medicine depend on the advances in the capabilities of fluorescence measurements. As examples, the sensitivity of many clinical assays is limited by sample autofluorescence, single-molecule detection is limited by ...
